Comparison of three techniques for simultaneous intraocular lens implantation in subluxated cataract surgery: Transconjunctival intrascleral, Z-suture knotless transscleral, and Cionni capsular tension ring assisted.

PURPOSE: To evaluate and compare the clinical outcomes of three different methods of intraocular lens (IOL) implantation in the surgery of subluxated cataracts.

METHODS: In this retrospective, comparative, clinical interventional study, the medical records of patients who underwent IOL implantation with sutureless 27-gauge needle-assisted transconjunctival intrascleral (Group 1), Z-suture knotless transscleral (Group 2), and Cionni capsular tension ring (Cionni-CTR) assisted (Group 3) simultaneously with subluxated cataract extraction between June 2010 and June 2022 were evaluated. Demographic characteristics, follow-up times, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical and cylindrical refractive values, and spherical equivalent (SE) values of three groups were compared. Intraoperative and postoperative complications were recorded.

RESULTS: There were 20 eyes in Group 1, 35 eyes in Group 2, and 40 eyes in Group 3. In all groups, statistically significant improvement was observed in postoperative UDVA and CDVA compared to preoperative values (each p < 0.05). There was no statistical difference between the groups in postoperative UDVA and CDVA values. (p = 0.130, p = 0.167 respectively). No significant difference was observed between the groups in terms of postoperative spherical, cylindrical, and SE values (each p > 0.05).

CONCLUSION: The study suggests that three different IOL implantation techniques for simultaneous IOL implantation in subluxated cataract surgery have similar effects on visual and refractive outcomes.
