Causes of failure of Visual Rehabilitation in Pseudophakic Patients: A Review of 100 Cases.
Pak J Ophthalmol Jan ;14(2):52-7.

Among the 100 cases included In this study, 87 achieved the best-corrected visual acuity of 6112 or better. Visual acuity between 6118 and 6/60 was achieved in 9 patients. 4 patients could not achieve visual acuity better than counting fingers. The causes for persistent poor visual acuity in these patients were age-related macular degeneration in 3, diabetic maculopathy in 3 and retinitis pigmentosa in 1 patient. These could not be detected preoperatively because of dense cataracts. One patient had a sudden loss of vision 2 weeks after surgery and was diagnosed as a case of central retinal artery occlusion. The main complications related to the procedure causing poor visual outcome were corneal decompensation in one patient inferior dislocation of IOL in one and cystoid macular edema in two patients. In one patient no cause for poor vision was detectable. We think amblyopia might be the cause for poor vision in this patient. This study not only puts emphasis on avoiding the peroperative complications, but also helps us in recognizing the significance of complete preoperative checkup both ocular and systemic, as well as preoperative patient counseling regarding the visual prognosis in those with preexisting detectable ocular pathologies.
