Results of coaxial phacoemulsification through a 1.8-mm microincision in hard cataracts.

摘要

BACKGROUND AND OBJECTIVE: To assess the results of coaxial phacoemulsification through 1.8-mm coaxial microincision cataract surgery (C-MICS) phacoemulsification with foldable intraocular lens implantation in eyes with hard cataracts in comparison to eyes with soft cataracts. PATIENTS AND METHODS: Group 1 consisted of 40 eyes of 40 patients with hard cataracts (grade >/= 4, Lens Opacities Classification System III scale) and group 2 consisted of 45 eyes of 45 patients with non-mature cataracts (grade .05). Mean endothelial cell loss was 11.37% +/- 12.87% in group 1 and 2.87% +/- 9.66% in group 2 (P < .05). CONCLUSION: Although density of cataract has an unfavorable influence on early postoperative corneal endothelial cell loss, it did not significantly influence final DCVA and surgically induced astigmatism. C-MICS is a safe and effective method of treatment of cataracts, including cataracts with hard nuclei, and usually leads to good functional outcomes.
