Name of the Procedure:

Iridectomy with corneoscleral or corneal section; optical (separate procedure).

Summary

An iridectomy is a surgical procedure where a small portion of the iris (the colored part of the eye) is removed. This particular type involves an incision in the cornea or the corneoscleral junction (where the cornea meets the sclera) to improve vision.

Purpose

An optical iridectomy is performed to address specific eye conditions that impair vision. The goal is to create a new pupil opening or to remove damaged portions of the iris, thereby improving the patient's ability to see clearly.

Indications

The procedure is indicated for patients experiencing:

• Blurred or impaired vision due to iris deformities.
• Certain types of glaucoma.
• Corrective needs following cataract surgery complications.
• Iris tumors or cysts.

Preparation

• Patients may need to fast for several hours before the surgery.
• Medication instructions will be provided, including possible adjustments to existing prescriptions.
• Diagnostic tests such as an eye examination, imaging studies, and measurements of intraocular pressure will be conducted.

Procedure Description

1. The patient is administered local anesthesia, possibly with sedation to ensure comfort.
2. A sterile drape is placed around the eye, and a device is used to keep the eyelids open.
3. An incision is made in the cornea or at the corneoscleral junction.
4. Specialized microsurgical instruments are used to remove a small, precise section of the iris.
5. The incision is closed using fine sutures or self-sealing techniques.
6. The eye is treated with antibiotics and anti-inflammatory medications to prevent infection and reduce swelling.

Duration

The procedure typically takes around 30 to 60 minutes.

Setting

Iridectomy is usually performed in a hospital operating room or a specialized outpatient surgical center.

Personnel

The surgical team typically includes:

• An ophthalmic surgeon.
• An anesthesiologist or nurse anesthetist.
• Operating room nurses and technicians.

Risks and Complications

Common risks may include:

• Infection.
• Bleeding.
• Increased intraocular pressure.
• Swelling or inflammation of the eye. Rare complications could involve:
• Vision loss.
• Damage to surrounding eye structures.
• Corneal decompensation.

Benefits

The primary benefit is improved vision, which can be realized almost immediately after recovery, depending on individual cases.

Recovery

• Patients may be given an eye patch to protect the eye post-surgery.
• Follow-up visits are necessary to monitor healing.
• Medications may be prescribed to manage pain and prevent infection.
• Most individuals can resume normal activities within a few days to a week but should avoid strenuous activities until fully recovered.

Alternatives

Alternative treatments might include:

• Laser iridotomy, for less invasive management of similar conditions.
• Medical management of underlying conditions, such as medication for glaucoma.
• Other surgical interventions if the iris deformity is associated with more complex ocular conditions.

Patient Experience

During the procedure, patients should expect minimal discomfort due to anesthesia. Post-procedure, a mild throbbing sensation or discomfort is common, which can be managed with prescribed medications. Patients should avoid rubbing the eye and follow all post-operative care instructions diligently to ensure a smooth recovery.
