Abstract Details


To compare the method of scleral fixation using a hydrophobic foldable intraocular len(IOL)s with ring-shaped connecting bridges (enVista MX60, Bausch & Lomb) to that using PMMA IOLs (CZ70BD, Alcon Laboratories, Inc.)


Retrospective research / CHA Bundang Medical centre


Before IOL transscleral fixation, an anterior vitrectomy is performed. Two triangle-shaped scleral flaps are made. A double-armed 10-0 polypropylene suturing needle is anchored by a 24-gauge needle that is passed through the sclera using the routine ab externo technique. The mid-portion of the thread is pulled out through a main wound (2.8mm), then sutured at both inner ring-shaped connecting bridges (inner shorter rim). The IOL is carefully injected with a injector for the foldable IOL into the anterior chamber. All ties between 2 cut threads are made using a European death knot. Scleral fixation using PMMA IOLs was performed with the conventional method (6.0mm main wound).


This technique was performed in 25 eyes of 25 patients followed at least 3 postoperative months. The mean refractory difference after scleral fixation with the ring-shaped connecting bridge IOL and that with the PMMA IOL was -0.68D and -0.01D, respectively (p=0.059). No severe postoperative complication was noted.


Although, this technique is very safe and the postoperative myopic shift is not prominent with statistical significance, surgeons must take the possibility into account before the scleral fixation with the ring-shaped connecting bridge IOL.
