Summary
This study compared suture and sutureless iris fixation for dislocated intraocular lenses (IOLs). Both methods showed favorable outcomes, with sutureless fixation resulting in less astigmatism but longer surgery.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Intraocular Lenses
Background:
- Late intraocular lens (IOL) dislocation is a significant clinical challenge.
- Suture and sutureless iris fixation are common techniques for managing dislocated IOLs.
Purpose of the Study:
- To compare the clinical outcomes of suture versus sutureless iris fixation for dislocated IOLs.
- To evaluate surgical time, complications, and visual outcomes between the two techniques.
Main Methods:
- Retrospective cohort study of 60 patients over 10 years.
- IOL repositioning via Siepser slipknot suture technique or retropupillary sutureless iris claw IOL exchange.
- Assessment of anatomical, refractive, and visual parameters 6 months post-surgery.
Main Results:
- No significant differences in postoperative outcomes between suture and sutureless iris fixation.
- Sutureless IOL exchange had a shorter surgical duration (42.7 min vs. 62.9 min).
- Sutureless fixation resulted in significantly less postoperative corneal astigmatism (1.89 D vs. 1.31 D).
Conclusions:
- Both suture and sutureless iris fixation techniques offer favorable outcomes for dislocated IOLs.
- Sutureless iris claw IOL exchange provides a shorter surgical time.
- Suture fixation (IOL relocation) leads to reduced postoperative astigmatism.
