Abstract Details
Purpose:
At the ASCRS 2016, we reported on the L-shaped scleral pocket incision technique, which allows insertion/extraction of a polymethylmethacrylate (PMMA) intraocular lens (IOL) with a 6 mm optical diameter through a 3 mm scleral incision at the limbus. In the present study, we examined the usefulness of the L-shaped scleral pocket incision technique for cataract surgery using a 6-mm PMMA IOL or a 7-mm PMMA IOL.
Setting:
Juntendo University Shizuoka Hospital
Methods:
The subjects were 40 cataract patients (40eyes) who underwent phacoemulsification (PEA) and IOL insertion at Juntendo University Shizuoka Hospital between August and October 2015. We inserted a 6-mm PMMA IOL (6-mm group: 20eyes) through a 3x3 mm L-shaped scleral pocket incision, or a 7-mm PMMA IOL through a 4x3 mm L-shaped scleral pocket incision (7-mm group: 20 eyes). Postoperative changes of corneal astigmatism and complications were examined with an NIDEK ARK-1 auto ref/keratometer and a Tomey TMS-4 corneal topographer.
Results:
In the 6-mm group, corneal astigmatism was ��0.28D preoperatively, while it was 0.65D at 1 week postoperatively, 0.30D at 1 month postoperatively, 0.1D 2 at months postoperatively, and ��0.1D at 3 months postoperatively. In the 7-mm group, corneal astigmatism was ��0.33D preoperatively, while it was 0.85D at 1 week postoperatively, 0.59D at 1 month postoperatively, 0.34D at 2 months postoperatively, and ��0.16D at 3 months postoperatively. There was less induced astigmatism for the 6-mm group and the 7-mm group. Intraoperative complications included damage to the haptic at the time of insertion in one eye of the 7-mm group.
Conclusions:
The L-shaped scleral pocket incision technique can be a useful procedure for the insertion of both 6-mm and 7-mm PMMA IOLs in the developing countries.
