Monocular diplopia related to asymmetric corneal topography after laser in situ keratomileusis.

Purpose: To show a specific relationship between monocular diplopia and corneal refractive asymmetry after laser in situ keratomileusis (LASIK).

Methods: One hundred thirty-eight eyes of 98 patients who underwent LASIK for myopia between -2.12 and -17.

The use of dissimilar progressives in the management of presbyopia.

The management of anisophoria with bifocal spectacle correction has always presented a challenging refractive problem. Historically, practitioners have used dissimilar bifocal segments or bicentric grinding to neutralize induced vertical imbalance. We present a method of reducing anisophoria at near point with dissimilar progressive multifocals.

The effect of relative spectacle magnification on aniseikonia.

Purpose: The purpose of this article is to study the effects of modifying relative spectacle magnification to determine what effect this has on aniseikonia, binocularity, and visual comfort.

Methods: A prospective analysis of 34 aniseikonic patients was undertaken. The etiology of aniseikonia varied from physiologically occurring to induced.

Contemporary management of aniseikonia.

The diagnosis and management of aniseikonia has become a lost art. Refractive surgery and intraocular lens implantation has created a new patient population of anisometropia. Measurement of aniseikonia through instrumentation such as the space eikonometer is not readily available.

The illuminated high contrast macular grid: a pilot study.

Background: Analysis of visual disturbances in the central 10 degrees provides valuable data for the low vision clinician. Amsler grid testing in the visually impaired can be poorly visible and it can be difficult to transcribe results. Automated perimeters will accurately map retinal defects, but the equipment is expensive and this technique is time consuming.
