Abstract
Objective To observe the efficacy of phacoemulsification for the cataract patients with eye axis ≤ 22 mm. Methods Forty-four eyes of 38 cataract patients with the eye axis length of 18.41-22.00 mm underwent phacoemulsification. During the operation, the high quality viscoelastic agent was applied and the energy of ultrasound was reduced extremely. Postoperative visual acuity , intraocular pressure, anterior chamber depth, corneal endothelial cell density and complications were observed and analysed. Results The postoperative corrected vision were significantly improved(t=32.250, P=0.017). Compared with the preoperative IOP, that of 3 months postoperatively was lower, the difference was statistically significant (t=5.180, P=0.013). Anterior chamber depth postoperative obviously deepened compared with preoperative one (t=26.890, P=0.026). The postoperative corneal endothelial cell density was slightly lower than the preoperative one, but there was no statistically significant difference(t=0.86, P=0.18). Conclusion The surgery phacoemulsification for the treatment of cataract with eye axis of 22 mm or less is difficult. We should intraoperativly take necessary measures, for achieving good operation effect. Key words: Cataract; Short eye axis; Ultrasonic phacoemulsification; Effect
