A modified sutureless intraocular lens (IOL) scleral fixation technique using 6/0 prolene offers significant visual improvements and reduced complications. This safe and efficient method achieves surgical refractive goals with no major adverse events observed.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Intraocular Lenses
Background:
- Scleral fixation of intraocular lenses (IOLs) is crucial for managing complex cataract cases.
- Traditional methods can involve complications like haptic manipulation and slippage.
- A need exists for simpler, safer, and more efficient IOL fixation techniques.
Purpose of the Study:
- To evaluate the initial outcomes of a modified 6/0 prolene sutureless scleral fixation technique for IOLs.
- To assess the safety and efficacy of this novel double-flanged sutureless approach.
- To report the early surgical experience and visual results.
Main Methods:
- Retrospective review of 29 consecutive patients undergoing IOL surgery with the modified technique (December 2021 - October 2023).
- Evaluation of visual acuity (Early Treatment Diabetic Retinopathy Study letters), spherical equivalent (SE), astigmatism, and intraocular pressure at baseline and 1, 2, 3, and 6 months.
- Assessment of surgery-related complications during the follow-up period.
Main Results:
- Significant improvements in Early Treatment Diabetic Retinopathy Study letters and SE were observed postoperatively compared to baseline.
- Younger patients, those with preoperative lens drop, idiopathic cataracts, high baseline visual acuity, or low baseline SE showed the greatest visual gains.
- Patients with preoperative lens or IOL dislocation experienced greater SE improvement than those with subluxation.
- No cases of vitreous hemorrhage, cystoid macular edema, endophthalmitis, subluxation, or dislocation were reported.
Conclusions:
- The modified sutureless scleral fixation technique is a simple, safe, and effective method for IOL implantation.
- This technique minimizes haptic manipulation and slippage, leading to fewer postoperative complications.
- It facilitates completely sutureless surgery and aids in achieving desired surgical refractive outcomes.
