Purpose: To compare the two transscleral fixation (TSF) techniques of intrascleral pocket and conventionalscleral flap with conjunctival division techniques in terms of short-term clinical effects. Methods: This retrospective cohort study included all consecutive patients with aphakia in Gyeongsang NationalUniversity Hospital in Jinju, Korea, who underwent TSF between January 2012 and December 2014. Themedical records of all patients were retrospectively reviewed, and the endothelial cell count (ECC), refraction,best-corrected visual acuity (BCVA), intraocular pressure, slit lamp, and fundus examination results before and1 day and 6 months after surgery were recorded. The postoperative complications and visual outcomes werealso recorded. Results: The intrascleral pocket and conventional-flap groups did not differ significantly in terms of demographics,presurgical BCVA, or ECC. However, the intrascleral pocket group had a significantly lower BCVA at 1 dayand 6 months after surgery compared to the conventional-flap group. The two groups did not differ in termsof ECC 6 months after surgery. The intrascleral pocket group had no postoperative complications, but fivepatients in the conventional-flap group complained of irritation. In both groups, the intraocular lens was wellpositioned without tilting or subluxation, and astigmatism was significantly reduced at 1 day and 6 months aftersurgery. Conclusions: The intrascleral pocket technique of TSF does not involve conjunctival dissection and is a successfulmethod of sulcus fixation. It stably corrects the intraocular lens and is easy to perform, which helps toreduce operation time. It also reliably yields rapid visual acuity recovery without complications.
