PURPOSE
To report the visual outcomes of cataract surgery at the largest university eye hospitalin Tehran and to identify determinants of outcome.
METHODS
1285 records of age-related cataract procedures during 2006-2007 were randomlyselected and their baseline characteristics documented. A sample of 353 patients (405 eyes) wererecruited for an outcome visit with comprehensive examination two years post-operatively. Up tothree causes of visual loss (‘contributory reasons’) were listed, and the principle cause of ‘less thanexcellent outcome’ (best spectacle-corrected visual acuity <20/25) was defined as the primaryreason.
RESULTS
The mean age of the participants was 68.6 years and 50.7% were female.Phacoemulsification had been performed in 92.1%. Of the 405 eyes, 54%, 78%, and 97% of theeyes achieved a best-corrected acuity of ≥20/25, ≥20/40, and ≥20/200, respectively. Poorer visualoutcome was associated with older age, female sex, ocular comorbidities, surgically challengingeyes, long and short eyes (vs. eyes with normal axial length), and being operated on by a novicesurgeon. The leading contributory reasons to a less than excellent outcome – in a descending order– were foveopathy, posterior capsule opacification (PCO), corneal opacity and degenerativemyopia.
CONCLUSIONS
The outcome of cataract surgery (and phacoemulsification) in our center wasas desirable as that of the developed nations. Foveopathy, PCO, corneal opacity, degenerativemyopia, and age-related macular degeneration caused mild, moderate, and severe visual loss,respectively. |
