Abstract
Purpose: To evaluate the usefulness of four viscoelastic agents during phacoemulsification: 2% hydroxypropylmethylcellulose (HPMC) (Methocel®), 3% sodium hyaluronate with 4% chondroitin sulfate (Viscoat®), 1 % sodium hyaluronate (Healon®), 1.4% sodium hyaluronate (Healon® GA).Setting: Eye Clinic, Kreiskrankenhaus Bad Hersfeld, Germany.Methods: Two hundred patients, divided into four groups of 50 patients, received one of the viscoelastic substances during phacoemulsification and posterior chamber intraocular lens implantation. Patients were followed for 1 month. Visual acuity and intraocular pressure (IOP) were measured. The following were subjectively evaluated for each viscoelastic: corneal findings, anterior chamber reaction, visibility of intraocular structures and retention time during phacoemulsification, space maintaining ability, and removability and ease of injection.Results: Postoperative IOP and visual acuity were comparable among the four groups. Viscoat tended to trap nuclear fragments and air bubbles during the phacoemulsification procedure, which decreased visibility during surgery. Space maintenance and injection ease were significantly better with Healon and Healon GV.Conclusion: The high molecular weight viscoelastics (Healon and Healon GA performed better as viscosurgical tools during cataract surgery using phacoemulsification.
