Abstract Details



Purpose:

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.)

Setting:

Retrospective research / CHA Bundang Medical centre

Methods:

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).

Results:

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.

Conclusions:

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.
