ABSTRACT

@#AIM: To observe the efficacy of 23G minimally invasive system combined with phacoemulsification in the treatment of cataract complicated with vitreoretinopathy. <p>METHODS: Totally 96 cases(103 eyes)of patients with cataract and vitreoretinopathy were divided into observation group(48 cases 51 eyes)and control group(48 cases 52 eyes)by computer random number method. Observation group was given 23G minimally invasive system combined with phacoemulsification and vitrectomy, and control group was given conventional phacoemulsification and vitrectomy. The changes of best corrected visual acuity(LogMAR visual acuity), intraocular pressure and corneal astigmatism degree were observed before operation and at 1, 3 and 6mo after operation, and the complications were observed as well. <p>RESULTS:At 1, 3 and 6mo after operation, the LogMAR visual acuity in the two groups were lower than those before operation, and they were gradually decreased(<i>P</i><0.05), and the LogMAR visual acuity in observation group at the same time point were lower than those in control group(<i>P</i><0.05). The intraocular pressure in the two groups was lower than that before operation, and it was with a gradual decrease trend(<i>P</i><0.05), and the intraocular pressure in observation group was lower than that in control group at the same time(<i>P</i><0.05). Compared with before operation, the corneal astigmatism degree was increased significantly in the two groups at 1mo after operation(<i>P</i><0.05), and was decreased gradually to preoperative level at 6mo after operation and the corneal astigmatism degree at 1mo and 3mo after operation in observation group was lower than that in control group(<i>P</i><0.05). The incidence rate of postoperative complications in observation group was lower than that in control group(<i>P</i><0.05). <p>CONCLUSION: The 23G minimally invasive system combined with phacoemulsification has better efficacy than conventional surgery in the treatment of cataract complicated with vitreoretinopathy, and it is beneficial to the restoration of visual acuity, intraocular pressure, and corneal astigmatism degree, and it can reduce postoperative complications.
