■研究年龄相关性白内障患者植入复曲面双焦点或三焦点人工晶状体后的动态视力(DVA)。
■这是一项前瞻性随机对照试验。在入选并随机接受单侧超声乳化和环面三焦的124例患者中(939M/MP,CarlZeissMeditecAG,Jena,德国)或环形双焦点(909M,CarlZeissMeditecAG,Jena,德国)人工晶状体(IOL)植入,99例患者完成随访并纳入最终分析.术后,未校正和校正距离(UDVA和CDVA),中等(UIVA和DCIVA)和近(UNVA和DCNVA)静态视敏度,在一周时评估20、40和80度每秒(dps)的明显屈光和未校正和校正距离DVA(UDDVA和CDDVA),一个月三个月.
■术后三个月,三焦点和双焦点IOL组的UDVA分别为0.13±0.11和0.14±0.13,分别。明显更好的UIVA(三焦,0.17±0.13vs.双焦,0.23±0.13,p=0.037)和DCIVA(三焦,0.16±0.11vs.双焦,术后3个月,在植入曲面三焦比双焦点IOL的患者中观察到0.20±0.12,p=0.048)。在三个月时,植入环形双焦点IOL的患者在80dps(0.5607±0.2032)时获得的CDDVA优于三焦组(0.6573±0.2450,p=0.039)。术后20、40和80dps时的UDDVA和CDDVA与年龄(分别为p<0.05)和术后静态视力(分别为p<0.05)显着相关。
■复曲面三焦点IOL可提供更好的静态中间视敏度,复曲面双焦点人工晶体植入术提供了较好的高速远距离动态视力。
UNASSIGNED: To investigate the dynamic visual acuity (DVA) after implantation of toric bifocal or trifocal intraocular lens in age-related cataract patients.
UNASSIGNED: This was a prospective randomized controlled trial. Of one hundred and twenty-four patients enrolled and randomized to receive unilateral phacoemulsification and toric trifocal (939 M/MP, Carl Zeiss Meditec AG, Jena, Germany) or toric bifocal (909 M, Carl Zeiss Meditec AG, Jena, Germany) intraocular lenses (IOL) implantation, ninety-nine patients completed the follow-up and were included in final analysis. Postoperatively, uncorrected and corrected distance (UDVA and CDVA), intermediate (UIVA and DCIVA) and near (UNVA and DCNVA) static visual acuity, manifest refraction and uncorrected and corrected distance DVA (UDDVA and CDDVA) at 20, 40 and 80 degrees per second (dps) were evaluated at one week, one month and three months.
UNASSIGNED: Three months postoperatively, the UDVA were 0.13 ± 0.11 and 0.14 ± 0.13 in the toric trifocal and bifocal IOL group, respectively. Significant better UIVA (trifocal, 0.17 ± 0.13 vs. bifocal, 0.23 ± 0.13, p = 0.037) and DCIVA (trifocal, 0.16 ± 0.11 vs. bifocal, 0.20 ± 0.12, p = 0.048) were observed in patients implanting toric trifocal than bifocal IOL at three months postoperatively. Patients implanted with toric bifocal IOL obtained better CDDVA at 80 dps (0.5607 ± 0.2032) than the trifocal group (0.6573 ± 0.2450, p = 0.039) at three months. Postoperative UDDVA and CDDVA at 20, 40 and 80 dps were significantly associated with age (p < 0.05, respectively) and postoperative static visual acuity (p < 0.05, respectively).
UNASSIGNED: Toric trifocal IOL provides better static intermediate visual acuity, and toric bifocal IOL implantation provides better distance dynamic visual acuity at high speed.
