Purpose
To present a simple and effective solution for early postoperative rotational instability of toric intraocular extended depth-of-field (EDOF) lens (IOL) by inserting a Cionni modified capsular tension ring and interlocking the IOL haptic with the Cionni ring eyelet.
Setting
Pediatric and adult patients with myopic astigmatism who underwent surgery in our department at the Clinical Hospital for Ophthalmological Emergencies Bucharest or at the Alcor Clinic Bucharest using Toric EDOF lens
Methods
Retrospective analysis of visual and refractive data and surgical procedures.
Results
Intraoperative infusion of serum at the edge of the Quadruple-haptic Toric EDOF IOL produces a reproductible spinning motion of the EDOF IOL inside the lens bag. Interlocking the lens haptics with the Cionni ring eyelet produces a fixed lens-ring complex that cannot spin inside the lens bag due to the Cionni modified capsular tension ring. Analysis on 15 patients with a mean preoperative cylinder of 1.995 diopters (D) showed no statistical differences between early 3-day postoperative -0.217 D cylinder refraction and 1-month postoperative refraction -0.167D using Paired T Test p=0.619 >0.05. We present the technique in both adults with cataract and pediatric congenital cataract patients with increased axial length and myopic astigmatism.
Conclusions
Interlocking a Cionni ring with the EDOF Toric IOL prevents unwanted postoperative rotation of the IOL and enhances refractive stability of the results. The technique is easily reproductible, effective and adds little complexity to the surgery.
