PURPOSE To describe and analyze pediatric anterior capsulotomy techniques and make recommendations. METHODS Five anterior capsulotomy techniques were compared using a porcine model. Extensibility was measured by calculating the mean stretch-to-rupture circumference of each capsulotomy (20 eyes per technique) as a percentage of its circumference at rest. Edge characteristics were reviewed usin...
PURPOSE To assess the performance and optical limitations of standard, aspheric, and wavefront-customized intraocular lenses (IOLs) using clinically verified pseudophakic eye models. METHODS White light pseudophakic eye models were constructed from physical measurements performed on 46 individual cataract patients and subsequently verified using the clinically measured contrast sensitivity fu...
Purpose. To quantify the frequency of visual loss after successful retinal detachment (RD) surgery in macula-on patients in a multicentric, prospective series of RD. Methods. Clinical variables from consecutive macula-on RD patients were collected in a prospective multicentric study. Visual loss was defined as at least a reduction in one line in best corrected visual acuity (VA) with Snellen ch...
AIM/BACKGROUND Viewing the peripheral retina is the major problem in the repair of pseudophakic retinal detachments. Conventional buckling procedures in pseudophakic eyes are complicated by persistent retinal (re-) detachment and proliferative vitreoretinopathy (PVR) more often than in phakic eyes. METHODS Primary vitrectomy was performed in 33 consecutive cases for pseudophakic retinal detac...
AIM To compare the magnitude of apparent accommodation in pseudophakic eyes with refractive against-the-rule (ATR), with-the-rule (WTR) and minimum astigmatism. Factors associated with apparent accommodation were also examined in each group. METHODS In total, 87 pseudophakic eyes (87 patients) that underwent monofocal intraocular lens (IOL) implantation after uneventful cataract surgery were ...
BACKGROUND Refraction change of silicone oil (SO) tamponade in phakic and aphakic eye has been studied thoroughly; however, it is rarely studied in pseudophakic eye. In this paper we aimed to deduce a theoretical formula predicting refractive shift of silicone oil tamponade in pseudophakic eye and compared it with clinical findings. METHOD A theoretical formula was deduced through strict geom...
BACKGROUND Rhegmatogenous Retinal detachment (RRD) is relatively unusual in general population: annual incidence is 1:10,000. Objective of this study was to compare the anatomical and functional outcome of primary retinal re-attachment surgery in phakic and pseudophakic eyes. METHODS A case series comparative study was carried out at Al-Ibrahim Eye Hospital, Karachi from July 2008 to June 200...
PURPOSE To evaluate histological changes in the corneal stroma in pseudophakic bullous keratopathy. METHODS Twenty-eight patients (28 eyes) with pseudophakic bullous keratopathy underwent therapeutic penetrating keratoplasty at Shandong Eye Institute between January 2006 and November 2011. The patients were divided into two groups according to the duration of bullous keratopathy (<1.0 year gr...
PURPOSE To evaluate the difference in intraocular lens tilt and decentration measurements with 2 Purkinje meters. SETTING Vienna Institute for Research in Ocular Surgery, Hanusch Hospital, Vienna, Austria. DESIGN Prospective evaluation of diagnostic test. METHODS This single-center study included pseudophakic patients in 2 substudies in which 3 consecutive measurements were performed with...
