Purpose: We evaluated the short-term clinical outcomes of patients who underwent modified scleral fixation of an intraocular lens (IOL) using a scleral tunnel and groove.
Methods: From June 2016 to May 2017, 34 eyes of 34 patients who underwent modified scleral fixation of an IOL using a scleral tunnel and groove were retrospectively studied. We evaluated the best-corrected visual acuity (BCVA), corneal endothelial cell density, intraocular pressure (IOP), spherical equivalent, and postoperative complications at 1 week, 1 month, 3 months, and 6 months after surgery.
Results: The BCVA was 0.85 ± 0.83 logarithm of the minimal angle of resolution (logMAR) before surgery and 0.38 ± 0.61 logMAR at 6 months (p = 0.001). The corneal endothelial cell count was 1,955.12 ± 217/mm2 and 1,852.59 ± 190/mm2, before and after surgery, respectively, which was not significantly different (p = 0.186). Postoperative complications occurred in eight eyes (23.5%); IOP elevation in one eye (2.9%), IOL tilt or decentration in two eyes (5.7%), optic capture in four eyes (11.4%), and cystic macular edema in one eye (2.9%). The spherical equivalent showed myopic changes after surgery and decreased significantly over time (p = 0.001).
Conclusions: Modified scleral fixation of the IOL using a scleral tunnel and groove improved the BCVA, but did not significantly affect corneal endothelial cell loss. This procedure can be a good alternative to conventional scleral fixation of an IOL, which has advantages in shortened surgical time and easy surgical manipulation.
