Patients and Methods
We retrospectively reviewed 50 eyes of 47 consecutive patients with a preretinal membrane who underwent 20-gauge vitrectomy combined with phacoemulsification and aspiration (PEA) and intraocular lens (IOL) implantation and 50 eyes of 46 consecutive patients with the disorder who underwent 23-gauge vitrectomy combined with PEA and IOL implantation by the same surgeon (T.H.) (Table). The 20-gauge vitrectomies were performed from March 1, 2005 to June 30, 2006, and the 23-gauge vitrectomies were
Results
No patient required a suture at the 23-gauge sclerotomy site because of leakage and no sclerotomies were converted to the 20-gauge procedure.
A PVD was created intraoperatively in 17 (34%) of 50 eyes in the 23-gauge group and 15 (30%) in the 20-gauge group. Retinal breaks associated with the maneuvers performed to create a PVD occurred in 4 (24%) of 17 and 3 (20%) of 15 eyes in the 23- and 20-gauge groups, respectively, and were treated effectively with photocoagulation intraoperatively. No
Discussion
In the current study, there was rapid VA improvement and less surgically induced corneal astigmatism 1 week postoperatively in the eyes that underwent 23-gauge vitrectomy to remove preretinal membranes compared with the eyes treated with 20-gauge vitrectomy. Less induced corneal astigmatism during the first postoperative month may accelerate the improvement in VA.9, 10 The increase in postoperative astigmatism may be attributed to suturing at the entry port, and astigmatic changes after

In our institution, all vitrectomies for preretinal membranes were combined with phacoemulsification and aspiration and intraocular lens (IOL) implantation in patients 50 years of age and older.3 The indications for ERM surgery were the presence of symptoms and deformation of the fovea caused by ERM.
