• Common Names: Toric Intraocular Lens (IOL) Implantation
• Medical Term: Astigmatic IOL Implantation

Summary

Astigmatism Correcting Function of Intraocular Lens is a surgical procedure to implant a specially designed lens in the eye. This lens corrects astigmatism and other refractive issues, providing clearer vision without the need for glasses or contact lenses.

Purpose

The primary purpose of this procedure is to address refractive errors caused by astigmatism. The goals are:

• To provide clearer vision
• To reduce or eliminate the need for corrective eyewear like glasses or contact lenses.

Indications

The procedure is typically indicated for patients who:

• Have significant astigmatism impacting their vision.
• Are undergoing cataract surgery and want to correct astigmatism simultaneously.
• Seek to improve their vision accuracy and quality of life.

Preparation

Patients may need to:

• Undergo a comprehensive eye examination.
• Discontinue certain medications that may affect surgery.
• Fast for several hours before the procedure.

Procedure Description

1. The eye is numbed with local anesthesia.
2. A small incision is made in the cornea.
3. The natural lens is removed, often using phacoemulsification.
4. The toric intraocular lens is inserted and precisely aligned to correct astigmatism.
5. The incision is closed, often without sutures.

Duration

The procedure typically takes around 15-30 minutes per eye.

Setting

This procedure is commonly performed in:

• Hospital outpatient departments
• Ambulatory surgical centers

• Reduced dependency on glasses or contact lenses
• Enhanced overall quality of life, with benefits noticeable shortly after the procedure.

Recovery

Post-procedure care includes:

• Use of prescribed eye drops to prevent infection and reduce inflammation.
