Abstract :
Introduction: To evaluate the safety, effectiveness and complications of retropupillary fixated iris-claw
lens in aphakia management.
Results: The mean age of the patient was 62.2 years. 21 patients underwent primary iris claw lens
implantation. Out of them nine had hard cataract, four patients had subluxation>180 degree, four had
non dilating pupil with pseudoexfoliation and one had traumatic cataract as preoperative risk factor. All
patients had PCR or bag dialysis during surgery. Three patients underwent secondary IOL implantation.
In the immediate postoperative period all patients had stable IOL with 71% patients showing improvement
in visual acuity. Most common complication noted was pupillary distortion (seven). Others were corneal
edema (six), raisediop (three) and hypotony (two). All of them resolved following topical medications.
At six weeks follow up 87.5% patients had BCVA ranged between 6\12-6\6. Two patients had macular
edema.
Materials and Methods: This is a prospective, interventional study conducted between February-2017 to
May-2019. Total of 24 eyes of 24 patients were included and routine preoperative evaluation was done and
risk factors evaluated. Posterior capsular rent was efficiently managed by anterior vitrectomy and placing
retropupillary iris fixated lens. Postoperative visual acuity, intraocular pressure was recorded and assessed
for complications.
Conclusion: Our study shows retropupillary iris fixated lens is a simple procedure with less time
consuming and lower incidence of visual threatening complications. Therefore it is a safe, effective option
for management of aphakia in patients with in adequate capsular support.
