Keratoconus, Risks & Systemic Disease

Keratoconus, Risks & Systemic Disease

Keratoconus is a progressive degenerative disorder of the cornea whereby structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual spherical shape. Keratoconus can cause substantial distortion of vision, with multiple images, streaking and sensitivity to light all often becoming troubling to the patient. Usually, we diagnose keratoconus during the adolescent years. If both eyes are significantly affected, the deterioration in vision can affect the person's ability to drive a car or read normal print.

In most cases, we can fit specialized contact lenses to correct vision sufficiently to allow the person to continue to drive legally and likewise function normally. Further progression of the disease may require surgery, for which several options are available and most popular, including intrastromal corneal ring segments, corneal collagen cross-linking, and in about 25% of cases, corneal transplantation. Estimates of the rates for keratoconus range from 1 in 500 to 1 in 2000 people. Recent information alerts us to a number of demographic, ancestry and systemic risk factors. These include that those of African ancestry have a 57% greater risk of a keratoconus and Latino persons have a 43% greater risk of being diagnosed compared with a Caucasian population. Asians had 39% reduced risks of keratoconus and patients with uncomplicated diabetes mellitus (DM) had 20% less risk. Other conditions found to have significantly increased risk of developing keratoconus include sleep apnea and asthma.

Satisfaction with LASIK vs. Contact Lenses

Satisfaction with LASIK vs. Contact Lenses
Patients who have been wearing contact lenses have made the choice to minimize their dependence on eyeglasses, but still have many of the inconvenient aspects of contact lens and care to contend with. For contact lens wearers, the decision to have LASIK represents the desire to experience a lifestyle and convenience with independence and freedom from the hassle of BOTH glasses and contacts. But, how does satisfaction with LASIK actually compare with contact lens wear? Researchers reporting in the journal Ophthalmology assessed patient satisfaction and perceived outcomes of 1800 patients split into two groups-one continuing to wear contact lenses and the other having LASIK, through annual surveys administered over a 3-year period. Most contact lens users had worn them successfully ≥5 years. The proportion expressing strong satisfaction with their current vision correction method decreased from 63% at baseline to 54% at year 3 in the contact lens control group, whereas 88% of former contact lens wearers and 77% of former glasses wearers were strongly satisfied with LASIK at year 3. Patients 40 years of age or younger when they had LASIK were somewhat more likely to be strongly satisfied than older patients. LASIK significantly reduced difficulties with night driving and nighttime visual disturbances among former contact lens users and former glasses users. The proportion with dry eye symptoms at 1, 2, or 3 years after LASIK was not significantly increased relative to baseline contact lens wear but was significantly increased relative to baseline glasses use, consistent with many glasses users having tried and abandoned contact lenses because of latent dry eye problems. Compared with continued contact lens wear, LASIK significantly reduced the self-reported rates of eye infections, ulcers, and abrasions each year.

The overall conclusions then were that compared with contact lens wear, current LASIK technology improved ease of night driving, did not significantly increase dry eye symptoms, and resulted in higher levels of satisfaction at 1, 2, and 3 years follow-up.
