Meta Analysis[Comparison of Toric intraocular lenses and corneal incisional procedures for correction of low and moderate astigmatism during cataract surgery: A meta-analysis].
Objective: To systematically compare the effects of Toric intraocular lens (IOL) implantation and corneal incisional procedures on the correction of astigmatism during cataract surgery. Methods: A peer-reviewed literature search was implemented in MEDLINE, EMBASE, EBSCO, ScienceDirect, Trip Database, Ovid, and the Chinese databases including CNKI and Wanfang Data. The inclusion criteria were randomized controlled trials (RCTs) that compared the Toric IOL implantation and the corneal incisional procedures to correct low and moderate astigmatism during cataract surgery. ⋯ There was no significant difference in the risk of surgical complications between the Toric IOL implantation and the corneal incision correction for astigmatism (relative risk, 0.45; 95% CI, 0.07 to 2.95; P=0.40). Conclusions: The current evidence suggests that Toric IOL implantation is more effective in correcting astigmatism than corneal incisional procedures during cataract surgery and shows better postoperative visual acuity. However, they are similar in the risk of postoperative complications. (Chin J Ophthalmol, 2019, 55: 522-530).
