Highlights

Eye Rubbing Feels Good But Is Not Good For You
By Richard S. Hoffman, MD

Richard S. Hoffman, M.D.

Keratoconus is a degenerative condition of the human cornea in which progressive thinning and change in the shape of cornea develop with time. There is a wide range of clinical presentations of keratoconus ranging from barely perceptible changes to frank cone formation of the cornea requiring corneal transplantation. Keratoconus affects roughly one person in a thousand and it appears to have multiple causes that are both environmental and genetic. Individuals with keratoconus typically develop progressive nearsightedness and astigmatism resulting in blurring and shadowing of images. The condition can be easily treated with glasses or rigid gas-permeable contact lenses.

Despite considerable research, the exact cause for keratoconus remains unknown. One of the possible environmental factors that may contribute to the formation of keratoconus is aggressive eye rubbing. There appears to be a strong association of eye rubbing with keratoconus. Originally this was felt to be a symptom of keratoconus in that patients who developed the degenerative condition might rub their eyes due to the irritation of the eyelids from the cone-shaped cornea. The assumption here was that the keratoconus developed first and the eye rubbing occurred secondarily as a reaction to the condition. However, more evidence is accumulating that suggests that the act of eye rubbing may actually cause keratoconus in susceptible patients. The observation that keratoconus is associated with allergic type conditions such as asthma and eczema lends credence to the theory that allergy-prone individuals may be causing the corneal degeneration through aggressive eye rubbing. Other observations in individuals with Down Syndrome or retinal dystrophies who have been demonstrated to rub one or both eyes since birth and then develop keratoconus in the rubbed eyes also suggests the causal association.

Does this mean that eye rubbing is dangerous? In general, occasional eye rubbing is fine as long as it not excessive and aggressive. If you have been diagnosed with keratoconus, then eye rubbing should be eliminated. I personally have seen keratoconic patients whose disease progression has slowed or stopped after eye rubbing was halted. [ top ]


Flap over Flaps: What is the Best Way to do LASIK?
By Mark Packer, M.D.

Mark Packer, M.D

The LASIK procedure involves two steps. First, a thin layer of tissue called a flap is constructed on the surface of the cornea. Second, the flap is lifted and laser energy is used to reshape the bed of tissue beneath the flap to correct nearsightedness, farsightedness and/or astigmatism. The flap is then laid back in place and allowed to heal.

There are two methods of flap construction: the mechanical microkeratome, which is a very fine, rapidly oscillating blade, and the femtosecond laser, which is a source of pinpoint light energy. Debate continues today as to which method is best. According a 2010 survey of members of the American Society of Cataract and Refractive Surgery, 50% of LASIK in the US today is performed with the microkeratome and 50% is performed with the laser.1

While many refractive surgeons prefer to use a microkeratome for creating a LASIK flap, market indicators appear to be pointing toward a shift to reliance on femtosecond technology. Published studies continue to show at least equal visual outcomes for these two technologies that are used to create LASIK flaps.2

A review of published peer-reviewed, comparative scientific studies on the relative safety of the microkeratome versus the laser shows equivalence. For example, an 18-month study performed at the John A. Moran Eye Center, Department of Ophthalmology, University of Utah demonstrated that the complication rate was 14.2% in the microkeratome group and 15.2% in the femtosecond laser group (P = .5437).3 Similarly, investigation has shown that healing is the same regardless of the method used for flap construction.4

Studies of effectiveness have also generally shown equivalence of the microkeratome and laser. For example, a study performed at the Mayo Clinic showed that the method of flap creation did not affect visual outcomes during the first 6 months after LASIK. Patients did not perceive a difference in vision.5 Another study published in the American Journal of Ophthalmology last year demonstrated that there were no differences in corneal total high-order aberrations, spherical aberration, coma, or trefoil between methods of flap creation at any examination over 4- and 6-mm-diameter pupils. Uncorrected and best-corrected visual acuity did not differ between methods at any examination and remained stable postoperatively through 3 years. The femtosecond laser flap did not offer any advantage in corneal high-order aberrations or visual acuity through 3 years after LASIK.6 Other authors have concluded that corneal aberrations after myopic LASIK are similar after mechanical microkeratome and femtosecond laser flap creation. Visual acuity, refraction, and the optical quality of the cornea after LASIK remain stable through 4 years postoperatively regardless of the method of flap construction.7

There may, however, be advantages for the laser in certain circumstances. One recent publication showed slightly better results in hyperopic LASIK,8 and another showed faster recovery in uncorrected acuity with the laser.9 Authors have also reported slightly better contrast sensitivity at higher spatial frequencies after laser flap construction.10 The one situation in which using the laser makes sense is when there is a limit to the refractive effect due to the thinness of the cornea. Surface ablation (for example, PRK) which does not require the construction of a flap at all may make the most sense in these cases, but the laser does have the ability to safely create a thinner flap and may allow the faster recovery time which is a significant benefit of LASIK.

LASIK remains a wonderful procedure to reduce or eliminate the need for glasses and contact lenses for good candidates, whether a laser or a microkeratome is used to construct the flap.

What You Can Learn From Your Family
by Annette Sims, M.D.

Annette Sims, M.D

As a glaucoma specialist, patients often ask me, “Should I be worried about my kids getting glaucoma now that I have it?” It is a great question since identifying risk factors such as family history is an important task in maintaining good eye health. My answer depends on the type of glaucoma the patient has. Most people are not aware there are many different types of glaucoma requiring different types of treatment. Patients may develop glaucoma from eye trauma, angle closure, retinal detachment, eye tumors, uveitis, diabetes, hyperthyroidism or prolonged corticosteroid use. Treatment options include eye drops to control eye pressure, lasers and various types of surgery. One of the more common forms of glaucoma is open angle glaucoma. There are still many unanswered questions about the genetics of open angle glaucoma. A few gene loci have been detected, but there is not a blood test at this time to check for glaucoma. One thing we know is siblings of patients diagnosed with open angle glaucoma have a tenfold increased risk of developing glaucoma over their lifetime. The Baltimore Eye Survey, a major study published in 1994, showed family history to be an important risk factor in open angle glaucoma. It was associated more highly in siblings than in parents or children. The results of the study support the screening for glaucoma in family members of patients with the disease.

What about macular degeneration? Macular degeneration appears to be hereditary in some families but not in others. We believe if you have a family history of macular degeneration, you have four times the risk of developing macular degeneration. There has been some research that claims if you have a first degree relative with late stage macular degeneration, you may develop macular degeneration at an increased rate at a younger age. The cause of macular degeneration is unknown. Risk factors that have been identified aside from family history are smoking, obesity, Caucasian race and age.

Lastly, if your parents had cataract surgery, will you need cataract surgery as well? Cataracts develop for a variety of reasons. They include long-term exposure to ultraviolet light, exposure to radiation, chromosomal disorders, trauma or systemic diseases such as diabetes. The most common form of cataracts is from advanced age called nuclear sclerosis. The Beaver Dam Eye Study looked to determine whether nuclear sclerosis could be explained by inheritance of a major gene. The findings suggested that several genes of modest effect may influence development of cataract. But the progression of cataract formation occurs in conjunction with environmental factors, most notably cigarette smoking. Other studies have highlighted the importance of blocking ocular exposure to ultraviolet light. In summary the etiology of cataract formation is complex, with environmental factors being just as important as family history.

In short, if you have one of the above mentioned ocular diseases, discuss this with family members. It may be a good idea to encourage them to have a screening eye exam. [ top ]
