Purpose

To evaluate the Yamane technique's effectiveness for scleral fixation (SF) and long-term outcomes and complications in managing complicated phacoemulsification surgery(CPS), secondary intraocualar lens (IOL) implantation (Sec-IOL), subluxated IOL (Sub-IOL), and dropped IOL (Dr-IOL).

Setting

This cohort study included 55 patients who underwent scleral fixation via the Yamane technique, performed by the same experienced ophthalmic surgeon between March 2021 and May 2023. Patients with prior histories of ocular trauma or surgeries beside phacoemulsification were excluded to maintain the study integrity. Ethical approval was granted by the Institutional Review Board of Istanbul Medeniyet University, and informed consent was acquired from all participants.

Methods

Patients undergoing SF for CPS (n=15), Sec-IOL (n=10), Sub-IOL (n=12), and Dr-IOL (n=18) were assessed. Evaluations included best corrected visual acuity (BCVA), Intraocular pressure (IOP), and complications and complications management settings over a minimum follow-up of 3 months.

Results

Demographic and baseline ocular profiles were consistent across groups with no statistical differences in age, gender, hypertension and diabetes presence, axial length, and anterior chamber depth. Median follow-up showed no difference (p=0.57). BCVA improved significantly in all groups (p<0.05) except Sec-IOL. All groups demonstrated significant IOP reduction following surgery. Early and late complication rates were similar across groups; transient corneal edema was the most frequent early complication, while late complications included cystoid macular edema and IOL dislocations. Management was predominantly medical; however, four patients needed surgical interventions for severe complications such as retinal detachment and endophthalmitis.

Conclusions

The Yamane technique for SF is effective, yielding significant improvements in BCVA and reduced IOP, with low rates of early and late complications. This technique showed no differences in complication rates among different surgical scenarios. In addition, most complications can be managed medically, while few required second surgery that showed a favorable outcome.
