Toric intraocular lenses: Evidence-based use

Area of Science:

• Ophthalmology
• Refractive Surgery

Background:

• Uncorrected refractive astigmatism significantly impairs visual acuity.
• Standard spherical intraocular lenses (IOLs) do not address corneal astigmatism, leaving residual refractive errors.
• Toric IOLs offer a solution by correcting pre-existing corneal astigmatism.

Purpose of the Study:

• To provide guidance for surgeons on the appropriate selection of eyes for toric IOL implantation.
• To outline methods for calculating the required IOL cylinder power.
• To detail surgical techniques and complication management for toric IOLs.

Main Methods:

• This is a review article, synthesizing existing information and best practices.
• Information covers patient selection criteria for toric IOLs.
• Methods include IOL power calculation, surgical techniques, and post-operative management.

Main Results:

• Appropriate application of reviewed information enables routine correction of visually significant astigmatism.
• Toric IOLs can lead to spectacle-free vision in pseudophakic patients.
• Successful implantation relies on careful patient selection and precise surgical execution.

Conclusions:

• Toric IOLs are effective in correcting corneal astigmatism, enhancing visual outcomes.
• Surgeons can achieve consistent correction of detrimental astigmatism with proper application of these guidelines.
• This approach contributes to improved quality of life for patients by reducing dependence on corrective eyewear.
