Clinical observation on ciliary sulcus suture fixation of intraocular lens with scleral tunnel technique

AIM:To observe the clinical effect of ciliary sulcus suture fixation of intraocular lens(IOL)with the scleral tunnel technique.METHODS: The clinical data of 36 patients(38 eyes)who underwent ciliary sulcus suture fixation of IOL with the scleral tunnel technique in our hospital from May 2021 to September 2023 were retrospectively analyzed. The patients were followed up for a total of 3-26 mo. The postoperative IOL position, visual acuity, refraction, intraocular pressure and complications were observed, and the results of tear film break-up time(BUT), corneal fluorescein staining(FL)and Schirmer Ⅰ test(SⅠt )were evaluated.RESULTS: The uncorrected visual acuity and best corrected visual acuity of all eyes were improved at 3 mo after surgery(all P<0.01). The differences of BUT and FL score before operation, and at 1 and 3 mo after operation were statistically significant(all P<0.05). Postoperative slit lamp examination showed the IOL of all eyes remained well positioned, and no suture erosion was observed.CONCLUSION: Ciliary sulcus suture fixation of IOL with the scleral tunnel technique is a safe, efficient, and minimally invasive procedure.
