Summary
Simplified intraocular lens insertion avoids tucking haptics, reducing stress and distortion. This technique enhances the safety and accuracy of implanting the 13 mm SI-26NB lens.
Area of Science:
- Ophthalmology
- Biomedical Engineering
Background:
- The SI-26NB intraocular lens (IOL) features modified C-configuration haptics.
- Current insertion techniques require tucking these haptics within the folded optic.
- This maneuver induces stress and potential distortion, leading to IOL decentration.
Purpose of the Study:
- To present a modified surgical technique for SI-26NB IOL insertion.
- To eliminate the challenging haptic-tucking step.
- To reduce surgical complications associated with IOL implantation.
Main Methods:
- A novel surgical approach for the 13 mm SI-26NB IOL was developed.
- The technique bypasses the need to tuck the modified C-configuration haptics into the optic.
- Scleral tunnel passage of the haptics was optimized to minimize stress.
Main Results:
- The modified technique simplifies the overall IOL insertion procedure.
- Eliminating the haptic-tucking step significantly reduces acute angle stress on the haptics.
- This approach mitigates asymmetrical distortion and subsequent IOL decentration.
Conclusions:
- A simplified technique for SI-26NB IOL insertion is feasible and effective.
- Excluding the haptic-tucking step improves surgical efficiency and IOL stability.
- This method offers a safer alternative for ophthalmic surgeons implanting this specific IOL model.
