BEFORE the introduction of enzymatic zonulysis by Joaquin Barraquer (1958), the normal procedure of senile lens extraction was either by intraor extra-capsular extraction, or, more recently, by the use of the erisophake. This latter operation can be done with much greater facility by the use of the enzyme, as has been demonstrated by Barraquer (1958), Cogan (1958), and Cogan, Symons, and Gibbs ...

OBJECTIVE To estimate the population health effects, costs and cost effectiveness of selected cataract surgery interventions in areas of the world with different epidemiological profiles. METHODS Effectiveness estimates are based on a review of the literature taking into account factors such as operative failure, complications and patient non-compliance. A population model was applied to foll...

This study was to evaluate the post operative astigmatism and visual acuity of patients after extra capsular extraction (ECCE) and phacoemulsification (PE) for the purpose of recommending the appropriate referral time for cataract extraction. Subject's hospital file data comprising 30 ECCE and 48 PE were collected and recorded according to gender and the technique employed in the surgical proce...

O cular hypotony is associated with significant visual dysfunction depending on its severity and duration. One etiology of hypotony is cyclodialysis cleft (CDC), a disinsertion of the longitudinal ciliary muscle fibers from the scleral spur. Originally described as a planned surgical treatment for intractable glaucoma, CDC may be observed following trauma or as an inadvertent surgical event fro...

BACKGROUND Corneal stromal pseudohypopyon is a rare entity. CASE A 65-year-old female developed a suture abscess in her pseudophakic right eye, three years after conventional extra-capsular cataract extraction with posterior chamber intraocular lens implantation. Pusfrom the suture abscess tracked down the corneal stromal layers and formed a pus level leading to the appearance of a corneal in...

Intraocular surgical procedures in general and filtering surgery in particular, predispose to cataract formation or accelerate pre-existing lens opacification thus the management of a visually significant cataract in a glaucoma patient who has had a previous trabeculectomy is a common clinical challenge, with the possibility that the intraocular surgery might result in filtration failure and lo...

The manual extracapsular extraction of the lens is the surgical technique that is most practiced for the treatment of cataract in sub-Saharan Africa. Learning this technique requires the creation of a surgical simulation unit within training institutes. We describe the development stages of a traditional simulation unit. For this purpose, we present a description of four steps involved in the d...
