Purpose To report the clinical characteristics and surgical outcomes of posterior lenticonus (PL) in the elderly patients.
Methods Four consecutive PL patients over 60 years were enrolled in this study.Clinical data on slit lamp examination and cataract surgical details were collected. Preoperative and postoperative best corrected visual acuity (BCVA) were analyzed.
Results Mean age of patients was (69.8 ± 8.1) years. Mean preoperative and postoperative BCVA was 0.05 ± 0.30 and 0.43 ± 0.38, respectively. The difference was statistically significant (p= 0.037). Slit lamp exmanition revealed that PL was unilateral and accompanied by posterior subcapsular cataract (PSC) in all patients. Dense opacified cortex ring underneath posterior capsule at the bottom of lenticonus was found in one case, mild PSC was found in the other three cases. A thickened fibrosis ring was left on posterior casule after careful aspiration of the cortex adherent to posterior capsule at the bottom of lenticonus in one case. No intraoperative or postoperative complications were found during follow-up.
Conclusions PL is rarely found and usually accompanied by PSC in the elderly patients.Cataract extraction could be successfully performed in the aged PL cases. Particular care should be taken during hydrodissection and aspiration of the posterior cortex bordering the bottom of lenticonus to avoid posterior capsular rent.
