Abstract
Purpose: To evaluate the effectiveness of a new combined ophthalmic viscosurgical device (OVD) in patients undergoing phacoemulsification.
Design: Consecutive case series study.
Material and Methods: This is a case series study of five eyes of five patients who underwent cataract surgery with a new combined OVD (2% hydroxypropyl methylcellulose - HPMC - mixed with 0.012% trypan blue). Data regarding clinical history, age, gender and best-corrected visual acuity (BCVA) were analyzed. All patients underwent a complete ophthalmologic examination. During the phacoemulsification the effectiveness of the viscostaining was analyzed at the time of the capsulorhexis. Postoperatively, parameters such as corneal edema and intraocular inflammatory reaction were evaluated.
Results: Three women and two men were included. The mean age of the patients was 69.6 ± 1.6 years (68 to 72 years). The mean preoperative LogMAR BCVA was 0.5 ± 0.14 (0.7 to 0.3). During the phacoemulsification there were no cases of “lost” capsulorhexis. Postoperatively, there were no patients with persistent corneal edema or with abnormal intraocular inflammatory reaction. The mean postoperative BCVA was 0.0 LogMAR units (Snellenequivalent - 20/20) in all cases.
Conclusions: Effectiveness of the viscostaining with this new OVD was satisfactory at the time of the capsulorhexis. HPMC mixed with trypan blue gives the impression of being safe during and after the phacoemulsification.
