Surgical correction of lens dislocation in children

Area of Science:

• Ophthalmology
• Pediatric Surgery
• Visual Impairment Research

Background:

• Ectopia lentis, a dislocation of the eye's natural lens, can lead to significant visual impairment in children.
• Nontraumatic causes of ectopia lentis require effective surgical interventions to restore visual function.
• Previous treatment modalities have varying degrees of success and complication rates.

Purpose of the Study:

• To evaluate the efficacy of the irrigation and aspiration (I/A) method for treating nontraumatic ectopia lentis in pediatric patients.
• To assess the outcomes of using the Keeler/SITE instrument as an alternative surgical approach.
• To determine the postoperative visual acuity and complication profile associated with these surgical techniques.

Main Methods:

• Retrospective analysis of 30 children treated with the irrigation and aspiration method.
• Inclusion of three children treated with the Keeler/SITE instrument for comparison.
• Preoperative and postoperative visual acuity measurements were recorded and analyzed.

Main Results:

• All patients presented with preoperative visual acuities of 6/21 (20/70) or worse.
• Postoperative visual acuity improved in 29 out of 30 eyes treated with I/A.
• 80% (24 out of 30) of eyes achieved postoperative visual acuity of 6/18 (20/60) or better; similar good results were observed with the Keeler/SITE instrument.

Conclusions:

• Both the irrigation and aspiration method and the Keeler/SITE instrument are effective surgical options for improving visual acuity in pediatric nontraumatic ectopia lentis.
• Amblyopia is identified as the primary complication, necessitating careful preoperative and postoperative management.
• The prognosis for achieving good postoperative visual acuity is favorable with these surgical interventions.
