Aim:
To describe a via pars plana anterior iris enclavation intraocular lens (IOL) fixation technique.
Methods:
A total of 35 consecutive aphakic vitrectomised patients (average age 71.12±10.12y) underwent pars plana vitrectomy (PPV) and via pars plana anterior iris enclavation IOL fixation.
Results:
The mean preoperative best corrected visual acuity (BCVA) was 0.11±0.14 logMAR, the mean postoperative BCVA was 0.07±0.11 logMAR. The preoperative mean spherical equivalent was 7.22±4.21 D. The final mean spherical equivalent was -0.25±0.15 D. No eyes had hypotony, retinal or choroidal detachment or endophthalmitis.
Conclusion:
This technique may be a safe and useful in the case of aphakia, and a prospective study would be useful to confirm this findings.
