Abstract:
AIM: To investigate the efficacy of small-incision horizontal space nuclear splitting surgery and phacoemulsification combined with regional refractive multifocal intraocular lens(MIOL)implantation in the treatment of hard nuclear cataract.METHODS:A retrospective analysis was performed for 288 patients(288 eyes)with hard nuclear cataract who admitted to our hospital from January 2022 to December 2023, and they were divided into control group(144 eyes treated with phacoemulsification and regional refractive MIOL)and observation group(144 eyes treated with small-incision horizontal space nuclear splitting surgery and regional refractive MIOL)according to different treatment methods. The operation time, pre- and post-operative best corrected visual acuity, astigmatism, central corneal thickness, corneal endothelial density, tear film function, and complications were compared between the two groups.RESULTS:There was no difference in operation time between the two groups(P>0.05). There was no difference in the preoperative and 3 mo postoperative best corrected visual acuity(all P>0.05), and the best corrected visual acuity of the two groups at 3 mo postoperatively was improved compared with the preoperative level(all P<0.05). There were differences in central corneal thickness, corneal endothelial density and astigmatism between the two groups at 1 wk and 3 mo after surgery(all P<0.05). There were differences in breakup time(BUT)and ocular surface disease index(OSDI)scores between the two groups at 1 wk after surgery(all P<0.001), and the incidence of complications in the observation group(4.2%)was significantly lower than that in the control group(18.1%; P<0.001).CONCLUSION:Both surgical methods can effectively treat patients with hard nuclear cataracts, and small-incision horizontal space nuclear splitting surgery combined with regional refractive MIOL implantation has less corneal damage and fewer complications.
