The visual function of femotosecond laser assisted phacoemulsification for cataract with high myopia / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM:To research the visual function of femtosecond laser assisted phacoemulsification in patients with cataract with high myopia. <p>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. <p>RESULTS: BCVA Compared with preoperative date, the postoperative BCVA were improved significantly(<i>P<</i>0.05). There were no significant difference between the 1d, 1wk, 1mo, 3mo, 6mo, 12mo postoperative CVA(<i>P></i>0.05). Accommodative function There were no significant difference between preoperative and postoperative negative accommodation(<i>P></i>0.05). Positive accommodation Compared with preoperative date, the 1d, 1wk, 1mo postoperative positive accommodation were no significantly different(<i>P></i>0.05), but the 3mo, 6mo, 12mo postoperative positive accommodation were significantly different(<i>P<</i>0.05). Convergence function Near point of convergence Compared with preoperative date, the 1d,1wk postoperative near point of convergence were significantly different(<i>P<</i>0.05), the 6mo, 12mo were no significantly different(<i>P></i>0.05). Significant difference was observed among other near point of convergence(<i>P<</i>0.05). Convergence scope Compared with preoperative date, the 1d, 1wk, 1mo postoperative convergence scope were no significantly different(<i>P></i>0.05), the 3mo, 6mo, 12mo were significantly different(<i>P<</i>0.05). AC/A Compared with preoperative date, the 1d, 1wk postoperative date decreased significantly(<i>P<</i>0.05). There was no significantly difference between the 6mo and 1a postoperative date(<i>P></i>0.05). Significant difference was observed among other AC/A(<i>P<</i>0.05). Visual stereoacuity Compared with preoperative date, the 1d, 1wk, 1mo postoperative visual steroacuity were no significantly different(<i>P></i>0.05), the 3mo, 6mo, 1a were significantly different(<i>P<</i>0.05). <p>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.
