高度近视并发白内障患者行飞秒激光辅助超声乳化术的视功能变化

目的：研究高度近视并发白内障患者行飞秒激光辅助超声乳化术的视功能变化。

方法：高度近视并发白内障患者97例97眼皆给予实施飞秒激光辅助白内障超声乳化联合人工晶状体植入术，于术前1d，术后1d，1wk，1、3、6、12mo检查最佳矫正视力、调节功能(负/正调节力、调节灵活度)、集合功能(集合近点、融合范围)、调节性集合与调节比率(AC/A值)、远距立体视锐度，进行统计学分析。

结果：术后各时间点最佳矫正视力均较术前提高(P<0.05)，术后各时间点间均无差异(P>0.05)。调节功能：术前及术后各时间负相对调节、调节灵敏度均无差异(P>0.05)； 术后1d，1wk，1mo正相对调节与术前均无差异(P>0.05)，术后3、6、12mo与术前均有差异(P<0.05)。集合功能：术后1d，1wk集合近点均较术前有差异(P<0.05)，术后6mo与术后12mo无差异(P>0.05)，余各时间点间均有差异(P<0.05)； 术后1d，1wk，1mo融合范围与术前均无差异(P>0.05)，术后3、6、12mo与术前均有差异(P<0.05)。术后1d，1wk AC/A值较术前均有差异(P<0.05)，术后6mo与术后12mo无差异(P>0.05)，余各时间点间均有差异(P<0.05)。术后1d，1wk，1mo远距立体视锐度与术前均无差异(P>0.05)，术后3、6、12mo与术前均有差异(P<0.05)。

结论：高度近视并发白内障患者行飞秒激光辅助超声乳化联合人工晶状体植入术，术后早期最佳矫正视力较术前明显提高，而视功能恢复相对缓慢。

The visual function of femotosecond laser assisted phacoemulsification for cataract with high myopia

AIM:To research the visual function of femtosecond laser assisted phacoemulsification in patients with cataract with high myopia.

METHODS:Ninety seven patients(97 eyes)of cataract with high myopia underwent standard femtosecond laser assisted phacoemulsification and intraocular lens implantation. The best correct visual acuity(BCVA), accommodative function(negative/positive accommodation, accommodative acuity), convergence function(near point of convergence, convergence scope), accommodative convergence/accommodation(AC/A), visual stereoacuity, were observed preoperatively and postoperatively.

RESULTS: BCVA: Compared with preoperative date, the postoperative BCVA were improved significantly(P<0.05). There were no significant difference between the 1d, 1wk, 1mo, 3mo, 6mo, 12mo postoperative CVA(P>0.05). Accommodative function: There were no significant difference between preoperative and postoperative negative accommodation(P>0.05). Positive accommodation: Compared with preoperative date, the 1d, 1wk, 1mo postoperative positive accommodation were no significantly different(P>0.05), but the 3mo, 6mo, 12mo postoperative positive accommodation were significantly different(P<0.05). Convergence function: Near point of convergence: Compared with preoperative date, the 1d,1wk postoperative near point of convergence were significantly different(P<0.05), the 6mo, 12mo were no significantly different(P>0.05). Significant difference was observed among other near point of convergence(P<0.05). Convergence scope: Compared with preoperative date, the 1d, 1wk, 1mo postoperative convergence scope were no significantly different(P>0.05), the 3mo, 6mo, 12mo were significantly different(P<0.05). AC/A: Compared with preoperative date, the 1d, 1wk postoperative date decreased significantly(P<0.05). There was no significantly difference between the 6mo and 1a postoperative date(P>0.05). Significant difference was observed among other AC/A(P<0.05). Visual stereoacuity: Compared with preoperative date, the 1d, 1wk, 1mo postoperative visual steroacuity were no significantly different(P>0.05), the 3mo, 6mo, 1a were significantly different(P<0.05).

CONCLUSION: The BCVA of patients of cataract with high myopia which underwent standard femtosecond laser assisted phacoemulsification and intraocular lens implantation improved obviously and early, but the visual function improved slowly.
