[Special indications for endocapsular artificial lens implantation]

Area of Science:

• Ophthalmology
• Surgical Innovation
• Biomedical Engineering

Background:

• Traditional intraocular lens (IOL) fixation methods, such as sulcus or capsular bag fixation, may be contraindicated in patients with specific ocular anomalies.
• Ocular anomalies present unique challenges for achieving stable and safe IOL implantation, potentially leading to complications or suboptimal visual outcomes.

Observation:

• This report details the successful endocapsular fixation of a posterior chamber lens in two pediatric patients.
• Patient 1 had lamellar cataract and a large total iridectomy; Patient 2 had nuclear cataract and normotensive congenital glaucoma.
• These cases were selected due to contraindications for conventional anterior chamber or sulcus fixation IOLs.

Findings:

• Endocapsular fixation provided a secure and effective method for implanting posterior chamber IOLs in these complex pediatric cases.
• The technique demonstrated successful visual rehabilitation without significant intraoperative or postoperative complications in the reported patients.
• This approach expands the surgical options for patients with challenging ocular conditions.

Implications:

• Endocapsular IOL implantation represents a valuable alternative for patients with significant ocular anomalies, including congenital coloboma, iris defects, and glaucoma.
• The technique is also indicated in cases of cystoid macular edema, diabetes mellitus, blood dyscrasias, anticoagulation therapy, and progressive iris atrophy.
• This method enhances the potential for successful visual restoration in a broader spectrum of patients requiring IOL surgery.
