Posterior Chamber Intraocular Lens (V2632)

Name of the Procedure:

Common names for this procedure include "Cataract Surgery with Lens Implant" or "Intraocular Lens (IOL) Implantation." The technical term is "Posterior Chamber Intraocular Lens Implantation."

Summary

This surgical procedure involves replacing the eye's natural lens, which has become cloudy due to cataracts, with a clear artificial lens known as an intraocular lens (IOL). This helps restore clear vision.

Purpose

The procedure addresses cataracts, a condition where the natural lens of the eye becomes cloudy and impairs vision. The primary goal is to replace the cloudy lens with a clear artificial one, thereby improving vision significantly and enhancing the patient's quality of life.

Indications

• Blurred or cloudy vision
• Difficulty with night vision
• Colors appearing faded
• Frequent changes in prescription glasses
• Vision deficits hindering daily activities
• Diagnosis of cataracts through an eye exam

Preparation

• Patients might need to fast for a few hours before the surgery.
• Temporary cessation of certain medications as advised by the doctor.
• Pre-operative eye exam and measurements to determine the correct IOL.
• Anti-inflammatory or antibiotic eye drops might be prescribed to use days before the procedure.

Procedure Description

1. Anesthesia: Local anesthesia to numb the eye, sometimes accompanied by a mild sedative.
2. Incision: A small incision is made on the side of the cornea.
3. Lens Removal: The clouded lens is broken up using an ultrasonic device and removed.
4. Lens Implantation: The artificial intraocular lens is inserted into the eye.
5. Closure: The incision is so small it usually heals naturally without stitches. Tools used include a phacoemulsification handpiece, intraocular lens, and microsurgical instruments.

Duration

The procedure typically takes about 15 to 30 minutes per eye.

Setting

This surgery is usually performed in an outpatient surgical center or a hospital.

Personnel

• Ophthalmic surgeon
• Surgical nurses
• Anesthesiologist or anesthesia nurse

Risks and Complications

• Infection
• Swelling or inflammation
• Glare, halos, or double vision
• Dislocated lens implant
• Retinal detachment (rare)
• Elevated intraocular pressure

Benefits

• Significant improvement in vision
• Reduction in glare and halos
• Enhanced ability to perform daily tasks
• Improved quality of life Most patients experience visual improvement within a few days after the procedure.

Recovery

• Use of prescribed eye drops to aid healing and prevent infection.
• Avoid rubbing or pressing on the eye.
• Wear a protective eye shield during sleep for a few days.
• Avoid strenuous activities and swimming for a few weeks.
• Follow-up appointments to monitor healing and adjust vision if necessary. Patients often resume normal activities within a few days, with complete recovery typically taking around 6 weeks.

Alternatives

• Observation for worsening symptoms if cataracts are mild.
• Stronger prescription glasses or contact lenses.
• Other types of cataract surgeries, such as laser-assisted surgery. Alternatives often depend on the stage of cataract development and the patient's overall health.

Patient Experience

During the procedure, the patient typically feels minimal discomfort due to local anesthesia. Post-procedure, mild itching and discomfort are common but manageable with prescribed medications. Vision may be blurred initially but improves as the eye heals. Proper pain management and adherence to post-operative care instructions contribute to a smoother recovery.
