Purpose
- 1. Assess uncorrected visual outcomes following refixation of dislocated single piece IOLs.
- 2. Evaluate the frequency of immediate and late postoperative complications.
- 3. Investigate postoperative centration and tilt of IOLs.
Setting
- Consecutive patients presenting with grossly subluxated or dislocated single piece IOLs were included.
Methods
- 9-0 polypropylene or Gortex sutures anchored dislocated IOLs using a modified ab-externo technique. The sutures were pierced through haptic optic junction of the single piece lens using threaded needle. The sutures are anchored to the sclera at 4 points. Postoperative uncorrected ans best corrected visual acuity were analysed. IOL centration and tilt were imaged using CASIA-1 anterior segment OCT.
Results
- Among 13 refixed eyes, mean preoperative BCVA was 0.62 logMAR units. Postoperative BCVA improved to 0.3 logMAR units (35 eyes). Mean IOL centration was 0.41 microns, and tilt was 6.26 degrees. Two eyes experienced transient vitreous hemorrhage, one required revision surgery for cheese wiring effect of IOL resulting in suture slippage.
Conclusions
- Closed globe refixation of IOLs using a modified ab-externo technique is safe and effective to refix dislocated single piece IOL with acceptable centration and tilt. This minimally invasive technique preserves the original IOL properties, allowing for rapid recovery.
