To evaluate the results of phacoemulsification and intraocular lens implantation after deep anterior lamellar keratoplasty (DALK).
Retrospective, consecutive, noncomparative, single-surgeon series.
Sixteen eyes of 16 patients were included (mean age: 51 years). Five eyes had phacoemulsification because of cataract, and 11 eyes for myopic refractive lens exchange. No intraoperative or postoperative complications were noted. Mean spherical equivalent (SE) improved from -8.69 D (SD 3.74) to -0.97 D (SD 1.13). Mean preoperative defocus equivalent (DE) improved from 10.32 D (SD 4.04) to 2.57 D (SD 0.92). Mean preoperative best spectacle-corrected visual acuity improved from 0.48 logMAR (SD 0.60) to 0.13 D (SD 0.005). Mean postoperative uncorrected visual acuity was 0.675 logMAR (SD 0.252). Safety index was 2.33, efficacy index was 0.70, and endothelial cell loss was not significant.
Phacoemulsification can provide safe and predictable visual rehabilitation for cataract and refractive errors resulting after DALK.
评估深层前板层角膜移植术（DALK）后白内障超声乳化吸除及人工晶状体植入的效果。
回顾性、连续性、非对比性、单术者系列研究。
纳入16例患者的16只眼（平均年龄：51岁）。5只眼因白内障行超声乳化吸除术，11只眼行近视屈光性晶状体置换术。未观察到术中或术后并发症。平均球镜等效度（SE）从-8.69 D（标准差3.74）改善至-0.97 D（标准差1.13）。平均术前散焦等效度（DE）从10.32 D（标准差4.04）改善至2.57 D（标准差0.92）。平均术前最佳矫正视力从0.48 logMAR（标准差0.60）改善至0.13 D（标准差0.005）。术后平均裸眼视力为0.675 logMAR（标准差0.252）。安全指数为2.33，有效指数为0.70，内皮细胞损失不显著。
超声乳化吸除术可为DALK术后因白内障和屈光不正导致的视力障碍提供安全且可预测的视力康复。
