PURPOSE: To describe a sample predictive model for intraocular pressure (IOP) following laser in situ keratomileusis (LASIK) for myopia and an IOP constant. METHODS: The records of patients that underwent LASIK for myopia and myopic astigmatism via WaveLight Allegretto Wave Eye-Q 400 Hz excimer laser and Hansatome XP microkeratome were retrospectively reviewed. Patients with no systemic or ocular disease other than myopia or myopic astigmatism were included in the study...

PURPOSE: The purpose of this study is to evaluate ocular, corneal, and internal aberration parameters in eyes with keratoconus (KC), forme fruste keratoconus (FFKC), and normal eyes. METHOD: In a prospective study, one eye of 110 patients with KC, 60 FFKC patients, and 150 healthy participants was evaluated using OPD-Scan II. Ocular, corneal, and internal higher-order aberrations were measured through a sixth-order Zernike polynomial decomposition. Receiver operating characteristic analysis was performed to evaluate the diagnostic ability of the aberration parameters in discriminating KC and FFKC from normal eyes...

BACKGROUND: Most studies have either excluded patients using contact lens or not taken their effect while analyzing post-collagen cross-linkage (CXL) changes. This study aims to study impact of CXL on lens fit in both quantitative and qualitative manner. OBJECTIVE: To evaluate changes in CL fit post-CXL and to correlate these changes with alterations in corneal topographic parameters. STUDY DESIGN: Prospective intervention study on 20 keratoconic eyes of 14 patients (age > 18 years), with mean follow-up of 6 months...

PURPOSE: To investigate the influence of preoperative biometric parameters on the accuracy of Haigis and SRKT formulae in predicting postoperative target refraction. METHODS: Retrospective analysis of 108 eyes (70 patients) underwent uneventful phacoemulsification surgery with implant of Alcon-SN60WF intraocular lens (IOL). Forty-five eyes were intentionally targeted to myopia (-0.75 to -1.25 dpt), while the others targeted between 0 and -0.75 dpt. Preoperative axial length and keratometry (K) were measured with optical biometry (LENSTAR-Haag-Streit)...

PURPOSE: This study proves the possibility of targeted use of the nonsteroidal anti-inflammatory drug lornoxicam to prevent the development of proliferative vitreoretinopathy (PVR). Triamcinolone acetonide (TA) was selected as a reference substance. METHODS: Wistar rats (N = 400) were used. PVR was modeled by intravitreal injection of dispase or concanavalin A. Lornoxicam or TA intravitreal administration was performed 20 min later. On the second and the third day, drugs were administrated systemic...

PURPOSE: The quality of cataract surgery delivered in sub-Saharan Africa (SSA) is a significant constraint to achieving the elimination of avoidable blindness. No published reports from routine SSA cataract services attain the WHO benchmarks for visual outcomes; poor outcomes (<6/60) often comprise 20% in published case series. This Delphi exercise aimed to identify and prioritise potential interventions for improving the quality of cataract surgery in SSA to guide research and eye health programme development...

OBJECTIVE: To assess clinical characteristics of patients at risk for recurrent nonspecific orbital inflammation (NSOI). METHODS: This was a retrospective comparison study with a 24-month follow-up, in a clinic-based population in rural India. The medical records at two eye care centers were searched from March 2001-2014. A total of 153 patients with recurrent NSOI, 107 of whom had a single recurrence (Group 1) and 46 of whom had multiple recurrences (Group 2).
