A longer view of secondary intraocular lens implantation with special emphasis on the role of the vitreous

Secondary Intraocular Lens (IOL) Implantation: Anterior Chamber versus Scleral Fixation Long-Term Comparative Evaluation

“…After secondary implantation with AC IOL, Hann et al reported vision of 6/12 or better in 70% of pa-tients (3). Many other authors were successful in achieving the preoperative visual status in as many as 60 to 93.8% of eyes of their patients, even after the second surgery of AC IOL implantation (4,16,18,19 (1,9,13). In our study, 36.66% (11/30) of patients achieved BCVA of 6/18 or better in Group I after a mean follow-up of 3 years.…”

“…Ciliary tenderness was the most common complication observed by us. Cystoid macular edema has been found to be the most common complication following any type of secondary IOL implantation (1,18,19,25). We also encountered this complication but it was not as common.…”

Secondary lens implantation

“…The visual outcome after secondary lens implantation in the present study was better or the same in 93.8% of the eyes; others had found values from 60 to 91% (Cozean et al 1980;Kraffet al 1983Kraffet al , 1987Shammas et al 1978). Four patients (6.2%) had a significant visual decline after the implantation; others had found a visual deterioration in 5--14% of the patients (Cozean et al 1980;Kraffet al 1983Kraffet al , 1987Shammas et al 1978).…”

“…Azar et al (1978) and Shammas et al (1981) found the same prevalence of CME in connection with vitreous loss. When the time interval between the cataract extraction and the secondary lens implantation is 6 months or more, the risk of CME is negligable (Cozean 1980;Shammas et al 1981;Wong et al 1987). Six of our patients (9.4%) developed a minifest or suspected CME despite the fact that none received a secondary implant prior to one year after the original cataract extraction.…”
