42. Outcomes of photorefractive keratectomy in patients with atypical topography Full Text available with Trip Pro

Outcomes of photorefractive keratectomy in patients with atypical topography Photorefractive keratectomy (PRK) is at risk of serious complications such as corneal ectasia, which can reduce corrected distance visual acuity. The rate of complications of PRK is higher in patients with atypical topography.To determine the outcomes of photorefractive keratectomy in patients with atypical topography.This cross-sectional study was done in 2015 in Shiraz in Iran. We included 85 eyes in this study (...) and -4.20±1.96 diopters in females; thus there was not statistically significant difference (p = 0.435).PRK is a safe and efficient photorefractive surgery and is associated with low complication rate in patients with atypical topography.

44. Photorefractive keratectomy after cataract surgery in uncommon cases: long-term results Full Text available with Trip Pro

Photorefractive keratectomy after cataract surgery in uncommon cases: long-term results To evaluate the efficacy and safety of the excimer laser correction of the residual refractive errors after cataract extraction with intraocular lens (IOL) implantation in uncommon cases.Totally 24 patients with high residual refractive error after cataract surgery with IOL implantation were examined. Twenty-two patients had a history of phacoemulsification and IOL implantation, and two had extra-capsular (...) cataract extraction with IOL implantation. Detailed examination of preoperative medical records was done to explain the origin of the post-cataract refractive errors. All patients underwent photorefractire keratectomy (PRK) enhancement. The mean outcome measures were refraction, uncorretted visual acuity (UCVA), best corrected visual acuity (BCVA) and corneal transparency and follow up ranged from 1 to 8y.The principal causes of residual ametropia was inexact IOL calculation in abnormal eyes with high

48. The Effect of Topical Substance-P Plus Insulin-like Growth Factor-1 (IGF-1) on Epithelial Healing After Photorefractive Keratectomy in Rabbits Full Text available with Trip Pro

The Effect of Topical Substance-P Plus Insulin-like Growth Factor-1 (IGF-1) on Epithelial Healing After Photorefractive Keratectomy in Rabbits To determine whether topical Substance-P (SP) plus insulin-like growth factor-1 (IGF-1) can improve corneal healing after photorefractive surface ablation in a rabbit.After a 9.0-mm corneal de-epithelialization using a combination of chemical (18% alcohol) and mechanical debridement, excimer photorefractive surface ablation was performed bilaterally (...) in eight rabbits (16 eyes) with an 8.0-mm ablation zone and 70-μm depth. The right eye was treated with SP (250 μg/mL) and IGF-1 (25 ng/mL) in hyaluronic acid, one drop twice a day, and the other eye treated with only hyaluronic acid. The epithelial healing process was documented photographically twice a day until healing was complete. Six rabbits were sacrificed 6 weeks after photorefractive keratectomy (PRK) and corneas examined histologically.Seven of eight rabbit eyes treated with SP/IGF-1 healed
