Abstract

Purpose : A novel technique for intrascleral intraocular lens (IOL) fixation using a microtube is reported.

Methods : This was a prospective interventional case series. Patients with aphakia, a dislocated IOL, or a subluxated crystalline lens were enrolled in this study. A microtube was transconjunctivally passed through the sclera and inserted into the ocular space. The center of the microtube passing through the ocular space was pulled out through an incision made for injecting the IOL and cut by microscissors. The IOL haptics were loaded into the disconnected end of the microtube and externalized by pulling out the opposite side of the disconnected end of the microtube. The tips of the IOL haptics were flanged and pushed back into the sclera. Best-corrected visual acuity (BCVA), corneal endothelial cell density, IOL astigmatism, and complications were analyzed.

Results : This study included four eyes of four patients: two cases of aphakia, one case of a dislocated IOL, and one case with a subluxated crystalline lens. The preoperative mean BCVA was 6/11 (0.26 logMAR) and mean postoperative BCVA was 6/7 (0.06 logMAR) at 1 month. The mean preoperative corneal endothelial cell density was 2,450 cells/mm2 and the postoperative corneal endothelial cell density was 2,248 cells/mm2 at 1 month. The mean IOL astigmatism was 0.50 ± 0.20 D. A postoperative incident was observed in one case of hypotony. In all cases, the haptics were well-fixed and the IOLs were centrally positioned.

Conclusions : Microtube-assisted intrascleral IOL fixation is an easily accessible, less invasive procedure.
