Toric IOL
Also written as: IOL — Toric Intraocular Lens
Specialized intraocular lens designed to correct astigmatism during cataract surgery through cylindrical power.
Full Definition
A toric intraocular lens is a premium IOL that incorporates cylindrical correction to address pre-existing corneal astigmatism during cataract surgery. Unlike standard monofocal IOLs, toric lenses have different powers in different meridians to counteract the irregular curvature of an astigmatic cornea. Proper documentation requires recording the lens power, axis of placement, and any rotational adjustments made during surgery. Editorial precision is crucial when documenting the specific toric model, as different manufacturers use varying naming conventions and power calculations.
Usage
Usage note: Always capitalize 'IOL' and specify the toric model and axis when documenting these procedures.
In Context
- "A toric IOL was implanted with the axis aligned at 90 degrees to correct the patient's 2.5 diopters of corneal astigmatism." — Operative report
- "Postoperative rotation of the toric IOL required repositioning to achieve optimal astigmatic correction." — Surgical complication note
