Outcomes of custom laser in situ keratomileusis: dilated wavescans versus undilated wavescans.

Purpose: To evaluate refractive outcomes of custom laser in situ keratomileusis (LASIK) based on undilated and pharmacologically dilated wavefront aberrometry with the Visx laser system.

Setting: Clinical refractive practice, St. Louis, Missouri, USA.

Ultra-wide-field imaging for cytomegalovirus retinitis.

Background And Objective: To compare the Optomap imaging system (Optos PLC, Dunfermline, Scotland) with conventional fundus photography in patients with cytomegalovirus (CMV) retinitis.

Patients And Methods: Patients treated at Rush University for acquired immune deficiency syndrome and CMV retinitis were studied prospectively. Conventional nine-field photography and Optomap ultra-wide-field photography were performed on the same day.

Reduced application time for prophylactic mitomycin C in photorefractive keratectomy.

Objective: To determine whether the duration of mitomycin C (MMC) 0.02% application affects visual outcome or the incidence of subepithelial haze in patients undergoing photorefractive keratectomy (PRK) with prophylactic administration of MMC.

Design: Retrospective, comparative case series.
