Purpose:
To evaluate the efficacy of iris fixation of dislocated intraocular lenses (IOLs).
Setting:
A tertiarty referral center. A retrospective study of 44 consecutive cases of dislocated IOLs that underwent iris fixation of the dislocated IOL.
Methods:
Forty-four consecutive cases of dislocated IOLs that underwent iris fixation of the dislocated IOLs. Demographic information, data regarding surgery and follow-up were retrieved from patient files. All eyes were operated on in a similar fashion by the same anterior segment surgeon (A.M.) - utilizing the McCannel suture technique and/or the Siepser slipknot technique. Main outcome measures were visual acuity improvement, surgically induced astigmatism and assessment of complications.
Results:
Ten eyes had a documented complication during primary cataract extraction. Pseudoexfoliation was present in 11 eyes (25%). History of ocular trauma and high myopia were present in 6 eyes (each). Excluding eyes with macular disease and very low visual acuity, visual acuity improved from 0.4 (± 0.05) logMAR to 0.24 (± 0.05) logMAR (p=0.047). Eyes with low pre-operative astigmatism did not worsen post-operatively (R square linear=0.8, p<0.01). Pupil ovalization was a major aesthetic complication (21 of 44 eyes). Major hemorrhagic complications were uncommon. One patient developed intermediate uveitis one year after IOL fixation.
Conclusions:
In this study of 44 eyes, iris fixation was proven to be a safe and effective method for treating dislocated IOLs. FINANCIAL DISCLOSURE?: No
