Abstract

Objective: To examine clinical characteristics of patients who underwent phacoemulsification assisted by trypan blue. Materials and methods: This is a case series about patients with white mature cataracts being treated with phacoemulsification assisted by trypan blue for enhancing visualization of the anterior capsule. Result: Average age is 56,63 ± 13,7 years old, in which the developing time of cataracts in the under 40 group is the fastest (3,8 ± 1 months). The median of visual acuity is hand movement (2,4 ± 0,63 logMAR). Mean of corneal endothelial cell density is 2805 ± 322 cells/mm². Median of anterior champer depth is 2,67 ± 0,74 mm with the axial length is 22,9 ± 0,95 mm. There are statistically significant correlations between the nuclear hardness grade and ultrasound time, also between the nuclear hardness grade and cumulative dissipated energy (r = 0,89, p < 0,01 and r = 0,97, p < 0,01, respectively). However, there is no significant correlation between the nuclear hardness grade and anterior champer depth (p = 0,34). Conclusion: The white mature cataract seriously impares visual acuity in a short time at various ages. In addition, there are deeper anterior champer depths in white mature cataract individuals. This is a challenging cataract surgery that includes many intraoperative complications.
