Use of scleral IOL fixation or CTR in children with ectopia lentis

New Management Strategies for Ectopia Lentis

Ectopia lentis refers to displacement of the crystalline lens in the setting of various systemic and metabolic disorders. A literature review was conducted to investigate the management of non-traumatic ectopia lentis in the pediatric population, particularly focusing on surgical intervention. Both limbal and pars plana approaches for lensectomy are well established in the literature. Surgical options for intraocular lens implantation in pediatric eyes with ectopia lentis include anterior chamber intraocular lenses and iris-fixated or scleral-fixated posterior chamber intraocular lenses. Recently, the use of capsular tension rings has also been described with promising results. Visual rehabilitation and treatment of amblyopia are essential for patients within the amblyogenic age group following surgical intervention.

Phacoemulsification using iris hooks and scleral fixation of the intraocular lens in patients with secondary glaucoma associated with lens subluxation

PURPOSE

We described the techniques and results of phacoemulsification using iris hook and scleral fixation of intraocular lens (IOL) in patients with secondary glaucoma associated with lens subluxation.

METHODS

Eight eyes of seven patients with secondary glaucoma associated with lens dislocation, who had undergone the surgery, were retrospectively reviewed.

RESULTS

At a mean of 23.5 months+/-13.6 (SD) after the surgery, the mean best-corrected visual acuity improved from 0.24+/-0.21 to 0.83+/-0.3, and mean intraocular pressure (IOP) was changed from 38.4+/-11.4 to 15.5+/-1.8 mmHg at the final examination. There were no vitreoretinal complications except cystoid macular oedema in one eye.

CONCLUSION

The technique appears to be safe and effective in terms of visual rehabilitation and controlling IOP in patients with secondary glaucoma associated with lens subluxation.

Isolated microspherophakia with optic disc colobomata

We describe a case of isolated bilateral microspherophakia with optic disc colobomata. A satisfactory outcome was achieved following uneventful lensectomy and scleral fixation of an intraocular lens.
