Toric Intraocular Lenses after Cataract Surgery

Toric Intraocular Lenses for Post-Transplant Astigmatism

Corneal transplants can be very successful at replacing diseased or damaged corneas. However, vision after a corneal transplant is often limited by high amounts of astigmatism. Treating this astigmatism is often difficult. Typically the amount of astigmatism is higher than can be corrected with glasses. Rigid contact lenses are often required. LASIK, PRK and astigmatic incisions in the cornea (astigmatic keratotomy) have all been tried with varying success.

This month, doctors at the Gavin Herbert Eye Institute at the University of California, Irvine, published a paper describing the use of commercially available, FDA approved toric (astigmatism correcting) intraocular lenses (IOL) during cataract surgery in patients with previous corneal transplant surgery.

Good candidates for this procedure are those who have had all transplant sutures removed and had corneal astigmatism that was stable, and for the most part symmetric and regular. (Image 1A shows topography that is both regular and symmetric. Image 1B is regular but not symmetric and image 1C is irregular.)

The study showed improvement in uncorrected vision (post-treatment average 20/40) and vision corrected with glasses only (post-treatment average 20/25). The images below, 1D and 1F, illustrate how toric intraocular lenses are positioned along the axis of corneal astigmatism.

While any intraocular surgery after corneal transplant can decrease the life expectancy of the graft, no complications or graft failures were seen during the course of the study. Not all types of astigmatism can be treated with this procedure.

This study highlights an effective treatment for regular symmetric corneal astigmatism after corneal transplant in patients needing cataract surgery.

Fuchs’ Dystrophy: Current Insights

What is Fuchs’ Dystrophy?

Corneal dystrophies are a debilitating group of progressive diseases that can ultimately deprive a person of sight. The cornea, which forms the front of the eye, is a window for vision, and dystrophies due to intrinsic defects in the corneal tissue cause this window to become opaque and hazy. Fuchs’ dystrophy, also known as Fuchs’ corneal endothelial dystrophy (FCED), is amongst the most commonly diagnosed corneal dystrophies requiring corneal transplantation. The ophthalmologist Ernest Fuchs first described the disease in 1910.

Who gets it?

The disease is rare, and it is difficult to predict who will get it. We know that it affects women more than men (3:1 ratio), older adults (older than 50 years of age), and those with a family history. There are forms in which there could be up to a 50% chance of transmission to children of parents with Fuchs’ dystrophy. Most cases, however, occur sporadically.

What causes it and how does it progress?

Although the cause of Fuchs’ dystrophy is still being studied, there are characteristic findings associated with it: small outgrowths on Descemet’s membrane called “guttae” or “guttata”, thickening of Descemet’s membrane, and defects in the endothelial cells (Figure 1).

fuchs dystrophy 1
Figure 1: Fuchs’ dystrophy can affect all layers of the cornea. Layers of the cornea from anterior to posterior, or frontside to backside, include (A) epithelial cells where blisters and bullae may form in late-stage disease, (B) Bowman’s layer where scarring can occur in late-stage disease, (C) stroma where corneal swelling occurs early in disease, (D) Descemet’s membrane where guttae form (arrows) and thickening occurs, and (E) endothelial cells that decrease in number and change shape and size with disease progression.

Descemet’s membrane is a thin corneal layer between the endothelial cell and the stromal layers of the cornea. Endothelial cells make up the backside of the cornea and function as a barrier and pump for keeping fluid out of the cornea and maintaining corneal clarity. As guttae accumulate on Descemet’s membrane, patients experience progressive loss and change in endothelial cells. Dysfunction of endothelial cells causes corneal swelling, which distorts vision. First, the back of the cornea swells, and eventually, swelling can reach the epithelial cells at the front of the cornea. Swelling can range from mild moisture accumulation, to painful “bullae”, or blisters. In very late-stage disease, significant corneal scar tissue can form and dramatically reduce vision. The progression to late stage Fuchs’ varies from person to person, but usually takes a couple of decades.

What are signs and symptoms?

A patient may be asymptomatic for years despite having guttae. Initial symptoms, including blurry, hazy, or cloudy vision, are typically due to corneal swelling from dysfunction of the endothelial cell layer. Patients may also experience glare or halos around light in the early stages just from the density of guttae. New studies suggest that patients can get glare and higher order aberrations from guttae without any corneal swelling. Symptoms tend to be worse on awakening, but usually improve throughout the day. This is because the closure of eyelids during sleep results in the accumulation of fluid in the cornea. For the same reason, humid weather can also worsen symptoms. As the disease progresses, poor vision may last longer into the day. There may be associated pain if blisters develop.

How is it diagnosed?

The presence of any of the above signs and symptoms, especially with a family history of Fuchs’, should prompt a consult with an ophthalmologist who will diagnose the disorder and follow its progression with regular checkups. An ophthalmologist will conduct a microscopic slit-lamp examination of the eyes, looking for guttae and Descemet’s membrane thickening (Figure 2).

fuchs dystrophy 2
Figure 2: Slit-lamp examination showing speckling pattern on the backside of the cornea characteristic of guttae in Fuchs’ dystrophy.

Special tests may be done to measure corneal thickness, a marker of swelling, or count endothelial cells to track disease progression (Figure 3 and 4).

How is it managed?

Management can be medical or surgical depending on symptoms. Patients may have mild or slow progression of disease that can be managed medically including over the counter salt solution drops (5% NaCl) to reduce corneal edema.

When there is late-stage disease, a corneal transplant may be necessary to improve vision. A corneal transplant replaces the patient’s corneal tissue with human donor corneal tissue. Donor corneas are readily available via excellent eye banks throughout the United States. The surgery is outpatient surgery with regular follow-up appointments and suture removal during the subsequent months. The postoperative healing of the cornea and vision stabilization can take up to a year.

Great strides have been made in the last decade in corneal transplantation surgery, giving patients better treatment options. Patients used to be limited to penetrating keratoplasty (PK), a full-thickness replacement of the cornea. We now have newer surgeries known as endothelial keratoplasty (EK), which is a partial-thickness transplant that replaces only the damaged part of the cornea (the endothelial layer). The different types of EK are DSEK (Descemet’s-Stripping Endothelial Keratoplasty) and DMEK (Descemet’s Membrane Endothelial Keratoplasty). The techniques vary by thickness of the transplanted tissue. The type of EK most appropriate is determined by the corneal surgeon and is variable on a case to case basis. Both types of EK surgeries provide comparable long-term visual results. In both surgeries, the patient’s diseased Descemet’s membrane and endothelial cells are stripped from the inner layer of their cornea. The thin lamellar donor graft is then inserted into the eye and positioned onto the back of the patient’s cornea via a gas or air bubble. The patient is then instructed to lie in a face up position for several hours post surgery during which time the bubble supports the graft until the new endothelial cell pumps begin to wake up and naturally adhere to the back side of the recipient cornea. Occasionally, the doctor may replace another air bubble into the eye the next day to allow more time for the graft to adhere. Visual recovery is on the order of 1-2 weeks in DMEK and 2-3 months in DSEK surgery. Rejection risk is still a possibility in EK surgery but has a much lower rate than traditional full thickness PK surgery.

Other surgical considerations depend on the presence of cataracts. Cataract surgery can worsen Fuchs’ dystrophy because of damage to the endothelial cell layer. For this reason, patients with cataracts and Fuchs’ requiring surgical intervention are often recommended to undergo cataract surgery before or at the same time as corneal transplantation to ensure the best outcome for the transplant.

Patients should work with an ophthalmologist to determine the best management plan. Ultimately, vast improvements in treatment options have given many Fuchs’ dystrophy patients the exciting opportunity to regain vision with improved healing times and reduced infection and rejection of the graft.

9 Ways To Relieve Cataract Surgery Stress

It’s an extremely rare person who would not feel nervous before surgery of any kind, even if it’s an outpatient procedure that will only take a few minutes. In the case of cataract surgery, the fear can be even worse than the procedure itself.


9 Ways to Relieve Cataract Surgery Stress
People who are under intense stress can suffer a range of symptoms, including irregular or racing heartbeat, nausea, upset stomach, difficulty breathing, and an inability to sleep. It can even affect your mind, causing you to forget important details about the operation, like advice on how to get ready or what to do after you come home from surgery.

Here are 9 ways to relieve cataract surgery stress:

1.  Just Think About It – Let’s start with the first, and most difficult, suggestion—change your own mind about how you feel. Admittedly, it takes a great deal of discipline that’s hard to muster in the face of great anxiety, but try to remind yourself how your sight will be saved after a relatively short, quick, and easy procedure. What you are about to go through will prevent you from going blind.

 

2.  Learn Everything You Can – For many, it helps to learn as much as possible about the surgery before it happens. Knowing exactly what’s going to happen and how others have dealt with what you’re going through can be a great relief. Knowledge may be all you need to relieve your anxiety.

 

3.  Talk to Your Surgeon – It almost always helps to just talk to someone, and who better than your surgeon? Who else knows every detail of the procedure you’re about to undergo? It’s fairly likely that your surgeon has performed many successful surgeries of this kind before, and he or she may have some stories of encouragement for you, as well as important and comforting knowledge of his or her own personal experiences.

 

4.  Imagine the End Result – It may help if you keep focused on what happens after, as if it’s already done and you can go home, the procedure over. This takes a great deal of imagination, rather than the discipline of thinking rationally about it, but if you have that level of imagination, it’s certainly worth trying.

 

5.  Alternate Methods – This encompasses a whole range of stress-reducing tactics that are not usually under the medical umbrella. Nevertheless, they have done a great many people a lot of good. Yoga, hypnosis, massage, acupuncture, acupressure, and other treatments have allowed those suffering preoperative stress to sleep better at the least.

 

6.  Herbal Supplements – A form of alternative treatment involving traditional ingredients to produce a more restful state. The herbs are often just infused into tea and drunk. While these supplements are generally called “all natural,” you should always consult your doctor before taking them, since they can have an effect on other medications you may be taking, including the anesthetic you are given before surgery.

 

7.  Have Some Fun – Do something fun to take your mind off of what’s about to happen. Whatever that specific thing may be is up to you, since an individual’s idea of fun differs from person to person. Whatever you generally do to take your mind off of things and unwind after a hard day may be just the thing to help you out before undergoing cataract surgery.

 

8.  Treat Yourself – In the same vein has doing something fun, do something that usually relaxes you. If you like going for long walks, do that the day before the surgery. Or listen to music that fills you with peace (or joy). Take a long bath. If it makes you feel relaxed or calm, it will help you deal with your anxiety.

 

9.  Distract Yourself – Once you get to the hospital, you’ll probably be waiting around, even if you get there right on time, giving plenty of time for stress to ramp up. You’ll do better if you keep yourself entertained, but the hospital waiting room is probably one of the more boring places on earth. Fix that by bringing something along to entertain yourself, like a book or some magazines, or even stream your favorite movie or podcast. You’ll probably want to bring more than one thing to do, in case the wait is long.

 

Stress adds complication to the body’s systems, and can therefore cause some complication in the upcoming surgery. Do what you can, whether you kick back with friends or take some herbal supplements, to help yourself get into the best mind space possible. Think about the positive outcomes, and you’ll do well.

 

What Are Scleral Contact Lenses?

In the beginning…of contact lenses…there were scleral lenses…only.

In the year 1887 a great gift was given to the world of sufferers of distorted vision resulting from corneal tissue that was irregular in shape from disease or trauma.
scleral lenses

The contact lens was invented nearly simultaneously by physicians working separately in Germany and in France. Working from drawings of Leonardo da Vinci (1508) and ideas of the British astronomer Sir John Herschel (1828), August Müller and separately Adolph Fick and Eugene Kalt blew glass shells to fit the outer eye and to some extent remedy their visual difficulties. These lenses rested on the conjunctiva of the eye above the sclera or white of the eye and were thus the first scleral contact lenses — the first contact lenses of any sort.

What are Scleral Contact Lenses?

The design and manufacture of scleral lenses has been a story of technological development significant for improvement in comfort, material, and affinity for the ocular surface.

For many years the lenses were partially molded and partially ground from the material of which hard contact lenses are made: PMMA (poly-methyl methacrylate) known as Plexiglas or Perspex. To form these lenses, like tooth implants, a plaster cast is made from a negative mold prepared from dental impression putty. The plastic would be heated and given the shape of the fitting surface of the lens from the plaster cast and then the power and edge curves would be ground onto the outside surface of the lens. Later came preformed trial sets not unfamiliar to those which we use today.

The current generation of scleral lens fitting began sometime in the last fifteen years with the mating of advanced corneal topography measurements, computer driven lathes and the observations of some very clever contact lens scientists. Proprietary designs of scleral lenses offering a variety of diameters, fitting philosophies, and multiple parameters are filling the gaps contact lens specialists have been wrestling with using smaller corneal contact lens designs for decades with less than optimal results. Most recently a firm has begun manufacturing lenses with a 3-D printer from an image generated from the eye. One eye…one lens, the lens is meant to fit like a fingerprint.

When discussing contact lens treatment, experts are experts because they agree that, any sort, size, or design of lens will have both positive and negative effects on the eyes and the tissues surrounding them. While it is true that many of the fitting and comfort issues confronted with corneal lenses of any size and design can be managed well with scleral designs, the scleral lens can also be difficult for some patients; for some eyes; for some conditions.

From the outset the larger size of the today’s scleral lens provides comfort on par with soft contact lenses for exactly the same reason: their size. Also, like soft contact lenses the scleral will not move around on the surface of the eye allowing the wearer a much more relaxed contact lens experience — there is no necessity to balance small corneal lenses between tense eyelids – vision can be enjoyed in any direction of gaze. The lenses will not fall off the eye and the increased size is a clear plus in finding a dropped contact lens.

On the other hand the quality of vision gained with scleral lenses specifically in cases of distorted corneae is far more comparable to that achievable with corneal GP lenses than with soft contact lenses in most cases.

Over the years my keratoconus patients have benefited from a series of contact lens breakthroughs that have variously improved the quality of their vision, their comfort with contact lenses, or in some other way the health of their eyes. Some years ago I “re-invented” the piggy-back system of contact lens wear which I summarized in 2008 in an article published in the Contact Lens Spectrum. Piggy-backers would place their vision restoring firm contact lens on top of a disposable daily wear lens of minimal focusing power. The soft lens would reduce the sensation of the firm lens while in many cases preventing the contact lens from abrading the cornea. More recently I have been successfully moving patients to scleral lenses because there is certainly less bother (only one lens per eye) and far less worry over corneal abrasions as the lens rests on the conjunctiva over the sclera and maintains a fluid cushion over the cornea itself.

Scleral lenses are finding their place in the world of contact lens fitting primarily to remedy vision problems from very irregular or otherwise damaged corneae both those caused by developing disease and trauma through injury or surgery. More and more, these lenses are requested by patients with normal eyes who want to enjoy the benefits provided by these lenses while participating in sports or other activities.

Scleral lenses are renowned for their greater comfort. In many cases a correctly fitted lens can be worn for many waking hours. Many patients have found that they benefit from exchanging the fluid from the reservoir from time to time throughout the day. The fluid that fills the lens-cornea space is sterile, non-preserved normal saline or in some cases saline with a non-preserved tear substitute added when needed for improved comfort.

A proper care regimen for scleral lenses is not different from that for any other contact lens manufactured from a firm oxygen permeable material. The lenses require cleaning upon removal, soaking in a recommended solution appropriate to the material of the lens and a periodic treatment to remove protein deposits. Of course, the exact care specifications will vary from patient to patient according to the evaluation of their contact lens specialist.

Just like any lens modality, the fitting requires expertise. Many who fit and dispense contact lenses rely on boxed soft lenses for their patients. When corneae become distorted those lenses will hardly fill the need. Greater expertise is required to fit rigid corneal lenses needed for these more problematic surfaces. The decision of the corneal lens expert to move on to the world of larger lenses is not of the same magnitude as that from boxes to corneal GP lenses. The investment is more a matter of time spent in discussion with the manufacturer’s fitting consultants, some reading, a webinar or two and keeping up to date with the lens designs that are available.

I was not among the first to use the current generation of scleral lenses, but when the opportunity knocked some years ago, I realized the importance of this form of contact lens and I believe I have positively influenced the quality of life of many of my patients.

Your Comprehensive Eye Exam

Your Comprehensive Eye Exam

Being able to see clearly is important to all of us. But it is also something we have a tendency to take for granted until we notice changes in our vision. The point of the yearly comprehensive exam is to monitor your eyes before any problems arise, and address any concerns that could affect your vision later. Here is what to expect at your next comprehensive eye exam.

An eye exam involves an external examination of your eyes followed by a series of tests designed to evaluate your vision and check for eye diseases. Each test evaluates a different aspect of your vision and includes specific tests for visual acuity, pupil function, muscle function, visual fields, eye pressure and viewing the back of the eye through a dilated pupil.
cross section of eye - eye exam
External Exam
The external examination consists of inspecting the eyelids, surrounding tissues and the eyeball including the sclera (white part of the eye), iris and cornea.

Visual Acuity & Fields
Visual acuity is your eye’s ability to detect fine details and see an in-focus image at a certain distance. A Snellen chart and a phoropter are used. The standard definition of normal visual acuity is 20/20. The term 20/20 comes from even sized objects that can be seen by a “person of normal vision” atvisual acuity eye exam the specified distance. For example, if a person can see at a distance of 20 feet an object that normally can be seen at 20 feet, then they have 20/20 vision. If they can see at 20 feet what a normal person can see at 40 feet, then they have 20/40 vision. For the visual acuity test each eye is tested separately to gauge your side or peripheral vision.

Pupil Functionpupil function eye exam
An examination of the pupil begins with inspecting your pupils for equal size, regular shape, reaction to light, and direct and consensual reaction (meaning the pupil of one eye constricts when the other eye is exposed to light).

Eye Muscle Function
Eye movement is assessed two ways. First by having you move your eye quickly to a target at the far right, left, top and bottom. Then by slow tracking which uses the ‘follow my finger’ test, which tests all the muscles that move your eye.

tonometer eye examEye Pressure Measurement
Intraocular pressure, or IOP, is measured using a tonometer to determine the fluid pressure inside your eye. This test provides information regarding your potential for glaucoma.

Viewing the Back of the Eyedilated eye - eye exam
Increasing the size of your pupil with eye drops (known as dilating your eyes) allows the doctor to have a larger view of the back of your eye, including the retina, as demonstrated by this diagram. This is very important for diagnosis and tracking of macular degeneration and diabetic retinopathy.

Eye Structureslit lamp eye exam
A special, high-powered microscope, called a slit-lamp, is used to view the structures of your eye clearly and in detail, enabling early diagnosis of a variety of eye conditions such as cataracts, presbyopia and corneal injury.

Taking care of your eyes, especially as you become older, is very important. Changes in vision may be gradual, or fast, but in both cases, early diagnosis is key to successful treatment and retaining your vision. It is suggested that individuals 40 and over have a comprehensive eye exam every one to two years. Exceptions would be if you have diabetes, in which case you should see your eye doctor yearly; or there is a family history of eye diseases such as glaucoma, macular degeneration, or corneal diseases, which may require more frequent visits to your eye doctor. If you have any degree of sudden vision loss, eye pain, or significant irritation, contact your eye doctor immediately.

6 Ways Women Can Stop Vision Loss

Women account for 53% of the world’s population. However, 2/3 of the blind and visually impaired people in the world are women. While 80% of these women are in developing countries, women in developed countries like the US are still more likely to face vision loss than men.
women can stop vision loss

Why are women more prone to eye disease than men?

Women are the caregivers in families, taking care of the health of family members over themselves. In addition, with many having jobs outside the home, they don’t feel they have the time to go to the doctor until something major happens, especially related to vision.

Women live longer than men are at greater risk for age-related eye diseases such as age-related macular degeneration (AMD), diabetic retinopathy, glaucoma and cataracts.

Women are more likely to develop several autoimmune diseases that can affect their eyes including, multiple sclerosis, lupus, rheumatoid arthritis and Sj?gren’s syndrome.

75% of new breast cancer diagnosed each year is estrogen-sensitive. A common part of estrogen-sensitive breast cancer treatment includes the prescription of tamoxifen. More studies are being done, but cataracts due to tamoxifen have been identified in about 10% of the patients taking the drug.

What can women do to lessen their chances for eye disease?

Know your family history as genetics play and important role in your eye health, so know what eye diseases run in your family. Let your eye doctor know so he can look for early warning signs that can help prevent of lessen the conditions in you.

Get routine comprehensive, dilated eye exams starting at the age of 40, to create a baseline for your doctor to work from. After that you can go every 2-4 years until the age of 60. At 60+ have a compressive, dilated exam every two years if you are symptom-free and low risk.

Eat healthy and exercise. It is important to maintain a healthy weight to reduce the risk of some eye diseases. Eating fresh fruits and vegetables is also important as they can contain carotenoids an some antioxidants that appear to help with vision retention. It should also be noted that in many studies, supplements did not show the same beneficial effects as whole foods.

Stop smoking! You not only increase your risk for cancer and heart disease, but smoking is the only thing besides advancing age that has been proven to be directly related to AMD.

Avoid ultraviolet light by wearing sunglasses (with wide-brimmed hats) and indoor glasses with UV protection. While everyone knows the sun is a source of UV light, so are electronic screens such as your TV, computer, tablet or smartphone. Prescription glasses and readers can have a clear UV coating put on them that will not distort your color vision. If you don’t need vision correction, there is eyewear with no correction that is coated to protect your eyes to avoid dry eye and retinal damage.

Use cosmetics and contacts safely. Always wash your hands first. Throw away old makeup and lens solutions. Do not share cosmetics or apply while driving. Make sure to clean your lenses thoroughly before putting them in your eyes.

Because women are relied upon to take care of the family, vision loss that can impact that responsibility can be devastating to the entire family. And later in life, when they may have outlived a spouse, the isolation and depression can destroy their quality of life as they try to cope on their own.

Reach out to women you know and remind them to take an active part in their own healthcare. Especially with regards to their vision, when women are at a higher risk of vision loss than men.

Medical Research Funding Needs Individual Donors

The Need for Medical Research Funding

About 1.75 million U.S. residents currently have advanced age-related macular degeneration with associated vision loss, with that number expected to grow to almost 3 million by the year 2020.

About 8.4 million individuals worldwide are blind from primary open-angle glaucoma, with that number expected to grow to almost 11 million by the year 2020.

About 22 million Americans have cataracts affecting their vision, with that number expected to grow to more than 30 million by the year 2020.

The economic impact of this increase of people with vision loss will be tremendous.  But right now scientist are working on ways to treat and eventually cure many eye diseases.  The only problem is the funding necessary to support this sight-saving research. Here is a look at the decline of medical research funding in the US and what you can do to help.
