CARTRIDGE-ASSISTED SCLERAL FIXATION OF A FOUR-LOOPED HAPTICS INTRAOCULAR LENS USING LOOPED SUTURES

Area of Science:

• Ophthalmology
• Surgical Techniques
• Intraocular Lenses

Background:

• Inadequate capsular support presents challenges for intraocular lens (IOL) fixation.
• Scleral fixation techniques aim to provide stable IOL placement.
• Suture exposure is a known complication of traditional scleral fixation.

Purpose of the Study:

• To describe a modified scleral fixation technique for 4-haptic foldable IOLs.
• To reduce suture exposure risks associated with IOL fixation.
• To enhance IOL centration stability in eyes with inadequate capsular support.

Main Methods:

• Retrospective interventional study of 9 eyes.
• Modified scleral fixation of a 4-haptic foldable IOL using 10-0 looped polypropylene sutures.
• Follow-up period of 10.89 months.

Main Results:

• Significant improvement in best-corrected visual acuity (BCVA) from 20/130 to 20/43.
• Mean IOL tilt of 0.27 ± 0.09 µm.
• Acceptable endothelial cell loss of 9.96% with no observed complications.

Conclusions:

• The modified technique provides reliable IOL positioning and visual improvement.
• Four-point fixation via small incision effectively eliminates suture-related complications.
• This method is suitable for eyes with inadequate capsular support.
