Intraoperative aberrometry-assisted refractive optimization of SFIOL.

Area of Science:

• Ophthalmology
• Refractive Surgery
• Intraocular Lens Implantation

Background:

• Scleral-fixated intraocular lens (SFIOL) is a common technique for insufficient capsular support.
• Sutureless SFIOL techniques are increasingly preferred over sutured methods.
• Existing SFIOL methods show significant variability in postoperative refractive outcomes, including residual refractive error and astigmatism.

Purpose of the Study:

• To present a novel technique for SFIOL implantation aimed at reducing postoperative residual refractive error.
• To improve refractive predictability and minimize astigmatism induced by IOL tilt.

Main Methods:

• Utilizing intraoperative aberrometry during SFIOL implantation.
• Adjusting the positioning and tension of the intraocular lens (IOL) haptics within scleral tunnels/flaps based on aberrometric data.
• Employing sutureless SFIOL with multifocal IOLs.

Main Results:

• The described technique aims to achieve minimal refractive error intraoperatively.
• Anticipated reduction in residual refractive error and induced astigmatism compared to conventional SFIOL techniques.
• Improved refractive outcomes in patients with insufficient capsular support.

Conclusions:

• Intraoperative aberrometry can be a valuable tool for optimizing refractive outcomes in SFIOL surgery.
• This technique offers a promising approach to enhance the predictability and accuracy of SFIOL implantation.
• Minimizing refractive error and astigmatism can lead to better visual function after SFIOL.
