A 15-month-old boy was referred to the Oculoplastic Clinic at Labbafinejad Medical Center for treatment of a bulging and deformed blind left eye. He was the result of a normal full-term pregnancy and there had been no ocular discharge at birth. Examination of the left eye revealed a keratinized and ectatic cornea bulging 9 mm anteriorly (Fig. 1). The right eye had a chorioretinal coloboma. Due ...

Purpose. To evaluate the safety, efficacy, and predictability of photorefractive keratectomy (PRK) on the corneal flap for correction of residual myopia following myopic laser in situ keratomileusis (LASIK). Patients and Methods. A retrospective study on eyes retreated by PRK on the corneal flap for residual myopia after LASIK. All eyes had no enough stroma after LASIK sufficient for LASIK enha...

PURPOSE To determine criteria for keratoconus or postoperative LASIK ectasia progression or improvement based on Pentacam HR (Oculus Optikgeräte GmbH) measured steepest corneal curvature. METHODS Sixty-one eyes from 41 patients with keratoconus or postoperative LASIK ectasia were evaluated. Each eye was measured 5 times with the Pentacam HR during the same clinic visit and the random measurem...

Keratoconus and other corneal conditions associated with progressive stromal thinning including keratectasia after laser-assisted in situ keratomileusis (LASIK) and pellucid marginal degeneration represent therapeutic challenges. Until recently, available therapies including contact lenses, epikeratoplasty, intrastromal corneal rings, and corneal transplantation targeted, in principle, the abno...

BACKGROUND The purpose of this study was to evaluate the safety and efficacy of ultraviolet A irradiation cross-linking on completion for cases of high myopic laser-assisted in situ keratomileusis (LASIK). METHODS Forty-three consecutive LASIK cases treated with femtosecond laser flap and the WaveLight excimer platform were evaluated perioperatively for uncorrected visual acuity, best correct...
