Clinical effects of femtosecond laser assisted phacoemulsification combined with regional refractive multifocal intraocular lens implantation in patients with high myopia and cataract
Objetive To observe the clinical effection and visual quality of femtosecond laser assisted cataract phacoemulsification(FLACS)combined with regional refractive multifocal intraocular lens(LS-313MF15,Holland)implantation in patients with high myopia and cataract.Method A total of 67 patients(90 eyes)with high myopia and cataract who underwent surgery in our hospital from March 2019 to March 2021 were retrospectively analyzed.They were divided into three groups,group A(20 patients 33 eyes):FLACS assisted LS-313MF15 implantation,group B(24 patients 28 eyes):ordinary cataract phacoemulsification combined with LS-313MF15 implantation,group C(23 patients 29 eyes):FLACS assisted mono-focal IOL(Proming,ALD)implantation.The patients were followed up for 3 months,the visual acuity recovery,spectacle independence,incidences of glare and halo at night,total higher-order aberration(HOA),defocus curve of the three groups were collected.Result At 3 months after surgery:the uncorrected distance visual acuity of group A and group B were significantly better than group C(P＜0.05),there was no significant difference between group A and group B(P＞0.05);There was no significant difference in corrected distance visual acuity among three groups(P＞0.05).Uncorrected intermediate and near visual acuity:group A was better than group B,group B was better than group C.The rate of spectacle independence:group A:96.9％,group B:92.8％,group C:20.6％,group A and group B were significantly higher than group C(x 2=53.076,P＜0.05).Incidences of glare and halo at night:group A:6.0％,group B:10.7％,group C:3.4％,there was no significant difference among three groups(x 2=1.239,P＞0.05).The HOA in group A and group C were significantly lower than those before surgery and lower than group B(P＜0.05).Defocus curve:compared to group B and group C,the curve of group A was flat and the visual acuity was good in different defocus ranges.Conclusion For the patients with high myopia combined with cataract,simultaneous implantation of LS-313MF15 assisted by FLACS could obtain better visual acuity,higher postoperative visual quality.
