Summary
Pars plana lensectomy-vitrectomy with or without an iris-sutured intraocular lens (IOL) for ectopia lentis in children offers similar visual outcomes. However, the use of an IOL carries a significant risk of dislocation.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Surgical Outcomes
Background:
- Ectopia lentis, a condition of lens displacement, requires surgical management in pediatric patients.
- Pars plana lensectomy-vitrectomy (PPL-PPV) is a common surgical approach.
- The use of intraocular lenses (IOLs) in conjunction with PPL-PPV for ectopia lentis is debated.
Purpose of the Study:
- To compare the visual outcomes and complication rates of PPL-PPV for pediatric ectopia lentis.
- To evaluate the impact of using a foldable iris-sutured IOL versus optical correction alone.
Main Methods:
- A retrospective study of 22 eyes from 12 pediatric patients with ectopia lentis.
- Patients underwent PPL-PPV, with 12 eyes receiving an iris-sutured IOL (Group L) and 10 eyes managed with optical correction (Group A).
- Outcomes assessed included visual acuity and complication rates.
Main Results:
- No statistically significant difference in achieving 20/40 or better visual acuity (Group A: 50%, Group L: 83%, P = .17).
- Mean postoperative visual acuity was comparable (Group A: 0.41 logMAR, Group L: 0.24 logMAR, P = .18).
- IOL dislocation occurred in 33% of eyes in Group L, with successful visual recovery after repositioning. No retinal detachments were observed.
Conclusions:
- PPL-PPV with iris-fixated IOLs for pediatric ectopia lentis provides visual outcomes comparable to optical correction.
- A significant risk of IOL dislocation exists with the iris-sutured IOL approach.
- Careful consideration of the risk-benefit profile is warranted when selecting IOLs for this patient population.
