In a point-counterpoint debate at the annual meeting of the American Academy of Ophthalmology, one clinician contended that the rate of post-LASIK ectasia is declining and that, with careful screening and other preparatory steps, the rate of ectasia can be kept very low. The counter-argument by another clinician suggested that the multifactorial basis of ectasia as well as unknown risk factors make it impossible to prevent a certain percentage of cases from developing.

In a prospective, randomized, contralateral study of 75 adults, eyes in which an aspheric IOL (AcrySof IQ model SN60WF, Alcon Laboratories) had been implanted demonstrated better mesopic contrast sensitivity, significantly less spherical aberration, and significantly less total higher-order aberrations compared with eyes in which a standard spherical IOL (AcrySof model SA60AT, Alcon Laboratories) had been implanted. Cumulative uncorrected visual acuity and best-corrected visual acuity were equivalent between both groups.

A new model can predict the percentage of people who will develop advanced age-related macular degeneration (AMD) at various ages. The model, which is based on well-established risk factors for the disease such as age, smoking, and genetics, considers high-risk, intermediate-risk, and low-risk genotypes. Genotypes are more predictive of the risk of developing advanced AMD than is age.

Scientists who produced a visual prosthesis giving rudimentary sight to the blind are to receive the Joseph von Fraunhofer Prize 2008 in recognition of their achievement.

Although fluorescein angiography (FA) and optical coherence tomography (OCT) are both effective ways to detect macular oedema (ME), when used in isolation they may miss subtle manifestations of the condition, according to a study published in the April 2008 issue of Retina.

The truth about LASIK

After hearing a variety of testimonies to discuss the post-market experience of LASIK, advisers to the FDA determined that lasers need improved patient labeling information. The advisers determined that the LASIK procedure itself is not the culprit; rather, it may be poor screening of possible candidates and misconstrued or insufficient information about the procedure relayed to patients. Ophthalmologists said that LASIK has a very high patient satisfaction rate and enumerated considerations for approaching studies of patient dissatisfaction.
