Postoperative Results Of P-Fixation Technique Aiming For Complication-Free Intrascleral Iol Fixation.

Secondary IOL implantation is associated with various complications. In this study, we evaluate the postoperative results of a modified flange fixation method using 27G forceps and a parallel scleral tunnel named the P-fixation technique aiming for complication-free intrascleral IOL fixation.

Juntendo University Shizuoka Hospital

 A modified flanged fixation using 27-gauge forceps was performed on 90 eyes of 85 patients between June 2021 and August 2022 at the Department of Ophthalmology, Juntendo University Shizuoka Hospital, Japan. The parallel scleral tunnel technique（65eyes : the parallel group）was compared with the angled scleral tunnel using the double-needle technique (25 eyes : the angled group). Visual acuity, complications, degree of IOL tilt were evaluated. Degree of IOL tilt was measured using CASIA2(TOMEY)

Regarding postoperative visual acuity, the parallel group produced more favorable results. The parallel group（3.30±1.58°） had a significantly less degree of IOL tilt compared to the angled group（5.24±1.74°）（p<0.01）. IOL fixation is as good as in-the-bag fixation, preventing IOL tilt without using special instruments such as a needle stabilizer. Complications in the angled group comprised IOL dislocation (one eye, 4%), vitreous hemorrhage (2 eyes, 8%), iris capture (2 eyes, 8%), and temporary ocular hypertension (one eye, 4%). However, no complications were seen in the parallel group. Although no scleral perforation was sutured without conjunctival incision, no leakage occurred

The P-fixation technique was useful for fixing an IOL in a good position without complications.
