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.
