OBJECTIVE To determine the visual outcome after surgery for persistent hyperplastic primary vitreous using modern vitreoretinal techniques. DESIGN Retrospective medical record review during a 5-year period (June 1992 to June 1997). Information recorded for each patient included age, medical history, sex, results of preoperative ocular examination, age at diagnosis, procedure performed, intrao...

Eighteen eyes in 17 patients with Fuchs' heterochromic iridocyclitis underwent cataract extraction with or without intraocular lens implantation (17 extracapsular and one intracapsular). Intraoperative complications included hyphaema, poor pupillary dilatations, and localised zonule dehiscence with vitreous loss. Only four eyes developed a marked anterior uveitus (two pseudophakic and two aphak...

A 38-year-old man with longstanding low intraocular pressure (IOP) in his right aphakic eye presented with severe pain and high IOP (35 mm Hg). On examination, visual acuity was light perception. The central and peripheral portions of the iris were directly opposed to the posterior corneal surface and synechial closure of the pupil margin. B-scan ultrasonography showed posterior vitreous detach...

In this population based study we have reviewed the files of all patients who underwent an extracapsular cataract extraction (ECCE) between 1984 and 1987, were normotensives prior to surgery, and were followed up for at least 10 months after the ECCE. From a total of 1047 operations 746 qualified for the inclusion criteria; of these, 16 (2.1%) were found to have a consistently raised intraocula...

PURPOSE To evaluate the clinical indications and postoperative results of iris-sutured posterior chamber intraocular lens implants performed during penetrating keratoplasty. METHODS Medical records were retrospectively reviewed for preoperative indications and postoperative results of 342 consecutive patients (366 eyes) who underwent iris suturing of a posterior chamber intraocular lens impla...

Minor differences in colour perception between pseudophakic, phakic, and spectacle aphakic eyes were identified by the Pickford-Nicholson anomaloscope and the Farnsworth-Munsell 100-hue test. The results suggest that pseudophakic eyes are more sensitive to red and less sensitive to blue than aphakic eyes corrected with spectacles. Spectrophotometer measurements reveal that the Rayner-Pearce pos...

AIM To explore the application of intraoperative wavefront aberrometry (IWA) for aphakia-based biometry using three existing formulae derived from autorefractive retinoscopy and introducing new improved formulae. METHODS In 74 patients undergoing cataract surgery, three repeated measurements of aphakic spherical equivalent (SE) were taken. All measurements were objectively graded for their qu...

PURPOSE To evaluate the clinical outcome in 29 patients (29 eyes) who underwent penetrating keratoplasty and scleral-fixation of an intraocular lens. METHODS The indications for penetrating keratoplasty with scleral-fixation of an intraocular lens were anterior chamber pseudophakic corneal edema, aphakic corneal edema, trauma, and corneal scars. Patients with pseudophakic corneal edema underw...
