PURPOSE: To evaluate the outcome and viability of a modified self-sealing scleral pocket technique for scleral fixation of an intraocular lens (IOL).
DESIGN: Retrospective interventional case series.
METHODS: A retrospective, interventional case series in which 81 eyes underwent this modified technique, performed in the previous 4 years. Cases included a dislocated IOL and an absent posterior capsule or subluxated cataract. Two diagonally opposed paralimbal, curved self-sealing scleral pockets were made 3 mm away from the limbus along with a vitrectomy. A multipiece IOL was used, and the haptics were fixed under the scleral pockets inside a linear scleral tunnel underneath the superficial scleral flap. The conjunctiva was opposed by using cautery. Postoperatively, anterior segment optical coherence tomography (AS-OCT) was performed in order to detect intrascleral hyper-reflective cross-section of the haptics and optic tilt. The optic position was re-evaluated using ultrasound biomicroscopy (UBM). Main outcomes were mean pre- and postoperative best corrected visual acuity (BCVA), postoperative astigmatism. Postoperative AS-OCT was performed to detect the position of the haptics and optics. UBM was done to recheck any optic tilt.
RESULTS: Mean pre- and postoperative BCVA were LogMAR 1.2 ± 0.59 and LogMAR 0.47 ± 0.3 (P < 0.001). Mean postoperative astigmatism was 1.27 ± 1.02 Dcyl. In AS-OCT, an intrascleral hyper-reflective shadow signified stable haptics without any optic tilt. UBM also showed a stable position of the IOL optic without any tilt.
CONCLUSIONS: This modified, simple way of scleral fixation of an IOL decreases the duration of surgery with minimal complication.
