tial for posterior dislocation of the donor corneal disc in aphakic eyes must be taken into consideration. Longer-lasting, higher-buoyancy gases (such as SF6) could be used as alternatives to air, but the possible toxic effect to endothelial cells should be elucidated.

purpose: to determine the indications for penetrating keratoplasty (pk) in iran over an 11-year period. methods: all eye bank records of patients who underwent pk from 1994 to 2004 at ophthalmologic centers throughout iran were reviewed. results: during this 11-year period, a total of 19,668 cases were operated. the most common indication for penetrating keratoplasty was keratoconus (34.5%), fo...

We report the correction of aphakia using an iris-claw, aphakic intraocular lens (IOL) fixated in a retropupillary location in a 17-year-old young man who suffered blunt trauma to his eye 5 months after penetrating keratoplasty (PKP). There were no intraoperative complications. At 21 months after implantation, the patient's uncorrected distance visual acuity was 20/28; his corrected distance vi...

A series of 54 non-myopic aphakic eyes with no signs of posterior vitreous detachment and 63 non-myopic aphakic eyes with various stages of posterior vitreous detachment was followed-up for a period of 6 months to 6 years. Over half of the eyes with no vitreous detachment when first examined developed various stages of posterior vitreous detachment during the follow-up period; in 10 eyes this w...

In a retrospective study of flat anterior chamber after cataract extraction, which was carried out at the University of Illinois Eye and Ear Infirmary (I959-I970), an incidence of 7-58 per cent. was found among 8,553 cases. Re-formation of the anterior chamber usually occurred after therapy with mydriatics (Reese, 1949), miotics, acetazolamide (Thorpe, 1954), or osmotic agents (Jaffe and Light,...

Post-traumatic aniridia combined with aphakia may be seen after globe injury. Aside from esthetic aspects, partial or total loss of the iris tissue may also be related to various degrees of glare and photophobia. Such patients suffer from severe visual impairment secondary to aphakia. Herein we describe a novel surgical technique for the management of an aphakic eye with traumatic aniridia for ...

126 cases of retinal breaks treated in our department by photocoagulation during a period of 10 years (1963-1973) were selected for a close annual follow-up. Eliminated from the study were cases of macular holes, breaks which developed in an eye after retinal detachment surgery, and cases in which a close follow-up was impossible for various reasons. The study includes symptomatic retinal break...

CASE REPORT We report one case of Brown-McLean syndrome. DISCUSSION In this case, a 71-year-old male developed a Brown-McLean syndrome after implantation of an anterior chamber lens in one aphakic eye. A phacoemulsification procedure was performed in the other eye without development of corneal clearance alterations in the next 7 years. The cause of Brown-McLean syndrome is still unexplained....

A procedure to determine the best image range of distances that can be obtained from an aphakic eye is presented. Corneal surfaces are calculated from videokeratographic data. Light distributions at different distances inside the eye are calculated with a near-field Fresnel diffraction algorithm. These patterns are evaluated using three different quality functions which quantify the appearance ...

The patient was referred to the Eye Clinic for a detailed ocular examination to evaluate a high-density structure found within the right globe. Pertinent history included poor vision in the right eye after being struck by a chain 7 years earlier. The left eye was normal. Visual acuity tests revealed the right eye to be aphakic. The pupil was mid-dilated and unresponsive to light, and a slit-lam...
