We report 2 patients who had radial keratotomy (RK) to correct myopia. The first patient developed a postoperative hyperopic shift and cataract. Nine years post RK, she had intracapsular cataract extraction and implantation of an Artisan aphakic intraocular lens (IOL). Twenty years post RK, hyperopia and astigmatism progressed to +7.0 -5.75 x 100 with a best corrected visual acuity (BCVA) of 20...

PURPOSE To document severe visual symptoms due to the dislocation of an iris-fixated aphakic anterior chamber lens using wavefront aberrometry. METHODS A patient complaining of severe visual blur and distortion due to a decentered Artisan iris-fixated anterior chamber lens was evaluated pre- and postoperatively after recentration. The patient underwent complete ophthalmic evaluation including...

Purpose We present a case of a patient with Soemmering ring after cataract surgery and a potential complication that can arise as a result of its presence. Observations A patient with history of ruptured globe status after repair and lensectomy, complicated by aphakic secondary open angle glaucoma, was referred for management of second injury to the same eye. This injury resulted in Soemmerin...

In the aphakic eye, with intact iris diaphragm, silicone oil has frequently caused a pupillary block. In this situation aqueous humour accumulates behind the iris and forces silicone oil through the pupil into the anterior chamber. An iridectomy at the 6 o'clock position can effectively prevent this pupillary block. The iridectomy allows free passage of aqueous to the anterior chamber which rem...

A study of 132 cases of aphakic retinal detachment (ARD) following mainly intracapsular cataract surgery has been made. Forty-nine cases (37%) were found to have vitreous incarcerated into the cataract section out of a total of 54 (41%) cases who had suffered a vitreous complication during cataract surgery. A study of the characteristics of ARD reveals that those cases having had a vitreous com...

A 2-year follow-up study was carried out on patients known to have developed aphakic macular oedema 6 weeks postoperatively, and the results were compared with those in a control group who had not developed oedema. Four eyes (12%) still had macular oedema, the visual acuities ranging between 6/5 and 6/9. There was no significant difference in visual acuities at 2 years between the 2 groups of p...

A review of 100 aphakic extended-wear soft contact lenses is presented for the period July 1980 to August 1981. Four previously successfully fitted patients with either American Optical Company's Sofcon or Cooper Laboratories' Permalens for extended wear developed corneal ulcers either directly under the lenses or shortly after removal. Three of the female patients were well controlled diabetic...

To study epidemiology, biometry and visual outcomes (with or without posterior capsulorhexis) in cases of pediatric traumatic cataract. This was a prospective observational conducted on 30 children cataract belonging to an age group less than 16 years. All patients were subjected detailed history ocular examination. Patients underwent surgery with intraocular lens (IOL) implantation. Posterior ...

Background: To evaluate the agreement in intraocular pressure (IOP) measurements by Ocular Response Analyzer (ORA) and Tono-Pen XL (TXL) with the Goldmann Applanation Tonometer (GAT) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (CCT) >600 µ. Methods: Thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...
