Use of a corneal shield improves the speed at which vision recovers after laser vision correction, according to a speaker at Hawaiian Eye. “Today’s post-PRK visual challenge is a great one,” Marguerite McDonald, MD, FACS, told colleagues, adding that it takes at least 4 days postoperatively for vision to reach a functional level. “[Patients] have blurry vision, they have hazy vision, and the refraction changes all over the place.”

Outcomes of Macular Hole Surgery with Short-Duration Positioning in Highly Myopic Eyes: A Case-Control Study – Corrected Proof

by  •  • 0 Comments

Purpose: To evaluate the outcomes of macular hole (MH) surgery with 3-day prone positioning in highly myopic eyes and to compare them with those from non–highly myopic eyes.Design: Retrospective nested case-control study from a cohort of 496 consecutive patients (496 eyes) who underwent surgery for MH.Participants: Forty-seven highly myopic eyes (with axial length >26 mm) were included in the study group and were matched for MH size and duration of symptoms with 47 non–highly myopic control eyes selected from the same cohort.Methods: All patients underwent pars plana vitrectomy, internal limiting membrane peeling, and 17% hexafluoroethane gas filling. Patients then were (Read more...)

The Use of Bowman’s Layer Vertical Topographic Thickness Map in the Diagnosis of Keratoconus – Corrected Proof

by  •  • 0 Comments

Purpose: To evaluate the use of Bowman’s layer (BL) vertical topographic thickness maps in diagnosing keratoconus (KC).Design: Prospective, case control, interventional case series.Participants: A total of 42 eyes: 22 eyes of 15 normal subjects and 20 eyes of 15 patients with KC.Intervention: Bowman’s layer 2-dimensional 9-mm vertical topographic thickness maps were created using custom-made ultra high-resolution optical coherence tomography.Main Outcome Measures: Bowman’s layer average and minimum thicknesses of the inferior half of the cornea, Bowman’s ectasia index (BEI; defined as BL minimum thickness of the inferior half of the cornea divided by BL average thickness of the superior half of (Read more...)
