Abstract:
PURPOSE: To compare the anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) and refractive change after cataract surgery between 3-piece and 1-piece aspheric intraocular lens (IOL) implantation. METHODS: The present study consisted of 16 patients (25 eyes) having 3-piece aspheric Tecnis(R) ZA9003 IOL and 21 patients (30 eyes) having 1-piece aspheric Tecnis(R) ZCB00 IOL. The ACD, ACV, and ACA were measured using an anterior eye segment analysis system (Pentacam, Oculus, Wetzlar, Germany) preoperatively and postoperatively 1 week and 1 month. Refractive outcomes were evaluated using an autokeratometer. RESULTS: When comparing the 3-piece (Tecnis(R) ZA9003) and 1-piece (Tecnis(R) ZCB00) IOL with the same optic, ACD, ACV, and AVA increased significantly after cataract surgery. The 1-piece IOL showed deeper ACD than the 3-piece IOL at postoperative 1 week and 1 month. Postoperative refraction showed slight myopic shift compared with target diopter, but was stable in both groups. CONCLUSIONS: There was significant increase in ACD, ACV, and ACA after cataract surgery in both IOL-inserted groups. Results showed stable refraction after cataract surgery in both groups. Consideration of the A-constant will be needed because of myopic change with the 1-piece IOL.
