Background:
The ideal and safe surgical method for Marfan-associated or idiopathic lens subluxations is still a matter of debate.
Patients And Methods:
Between 1990 and 1995, 23 eyes were operated for lens subluxations, mainly because of decreased visual acuity, but also because of conservatively uncontrolled secondary glaucoma. Marfan patients were 27.0 (5-62) years old at surgery; patients with idiopathic lens subluxations were 38.5 (11-63) years old. Surgical procedure depended on patient age and anatomical conditions.
Results:
All patients achieved an increase in visual acuity. Amblyopia existed in six patients. All problems due to glaucoma were controlled postoperatively. Our greatest concern was rhegmatogenous retinal detachment. It occurred in only one eye of a non-Marfan patient.
Conclusion:
The prognosis for lens surgery in Martan-associated and idiopathic lens subluxations is good. The implantation of a posterior chamber lens provides a good and secure means of optical rehabilitation. Our preferred primary transscleral suture technique guarantees high security and stability of position. Previously feared surgical risks have been reduced by modern surgical procedures.
Insights
Lens surgery for Marfan-associated and idiopathic lens subluxations offers good visual outcomes. Modern surgical techniques, including posterior chamber lens implantation and transscleral suture, ensure safety and stability.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Genetics
Context:
- Lens subluxation, associated with Marfan syndrome or idiopathic causes, presents surgical challenges.
- Debate continues regarding the optimal and safest surgical approach for these conditions.
- Secondary glaucoma can complicate lens subluxation, necessitating surgical intervention.
Purpose:
- To evaluate the safety and efficacy of surgical lens subluxation correction.
- To assess visual acuity outcomes and management of secondary glaucoma post-surgery.
- To compare surgical results in Marfan-associated versus idiopathic lens subluxations.
Summary:
- A study of 23 eyes operated between 1990-1995 for lens subluxations demonstrated successful visual acuity improvement.
- Posterior chamber lens implantation and a primary transscleral suture technique were employed, ensuring secure positioning.
- Postoperative glaucoma control was achieved in all cases, with a low incidence of complications like retinal detachment.
Impact:
- The findings suggest a favorable prognosis for lens surgery in both Marfan-associated and idiopathic lens subluxations.
- Modern surgical procedures have significantly reduced previously perceived risks.
- This study supports the use of posterior chamber lens implantation for effective optical rehabilitation.
