In a unilateral prospective clinical trial, 77 cases were randomized to receive a 3M multifocal IOL or a conventional monofocal implant. Multifocal cases had better uncorrected near vision than monofocal cases at the two to four month visit. Thirty percent of the multifocal cases had near acuity J1, while only 4% of the monofocal cases had that acuity. Eighty-seven percent of multifocal cases and 71% of monofocal cases had near acuities of J1 to J3. With distance correction in place, 54% of multifocal cases had near acuities of J1 to J2, while only 28% of monofocal cases had comparable acuities (P = .04). There have been no serious postoperative complications in either group.
在一项单侧前瞻性临床试验中，77例患者被随机分为两组，分别接受3M多焦点人工晶状体或传统单焦点人工晶状体植入。在术后两到四个月的随访中，多焦点组患者的未矫正近视力优于单焦点组。30%的多焦点组患者近视力达到J1，而单焦点组只有4%的患者达到该视力。87%的多焦点组患者和71%的单焦点组患者近视力在J1至J3之间。在进行远距离矫正后，54%的多焦点组患者近视力在J1至J2之间，而单焦点组只有28%的患者达到类似视力（P = 0.04）。两组均未出现严重的术后并发症。
