Comparison of the clinical outcomes after manual capsulorhexis on one eye and precision pulse capsulotomy on the other eye
摘要
To compare the clinical outcomes after manual continuous curvilinear capsulorhexis (CCC) on one eye and precision pulse capsulotomy (PPC) on the other eye in cataract surgery.
Methods60 eyes from 30 patients who underwent manual capsulorhexis on one eye (CCC group, N = 30) and precision pulse capsulotomy on the other eye (PPC group, N = 30) were retrospectively enrolled. Uncorrected and corrected visual acuity, manifest refraction, and corneal endothelial cell density were evaluated.
ResultsThere were also no significant differences between the two groups according to the change in the corneal endothelial cell density at 3 months after cataract surgery (p > 0.05). The horizontal diameter (mm) and area (mm2) of the capsulotomy of the PPC group were significantly smaller than those of the CCC at postoperative 1 day and 3 months (P < 0.05). The circularity of PPC group was significantly better than that of the CCC at postoperative 1 day and 3 months (P < 0.05) (Table
PPC was as safe as CCC and more efficient than CCC for making perfectly round capsulotomy. The initial capsulotomy size of PPC was smaller than that of CCC. PPC size decreased more than CCC after several months because it might damage the anterior capsule with thermal energy.
