Name of the Procedure:

Prescription and fitting of a corneal lens for aphakia, with medical supervision of adaptation (1 eye)

Summary

This procedure involves prescribing and fitting a contact lens specifically for individuals who have had their natural lens removed (a condition known as aphakia). The contact lens is carefully selected and fitted to ensure optimal vision and comfort, with medical supervision to monitor and adjust as needed for proper adaptation.

Purpose

Aphakia usually occurs after the removal of the eye's natural lens due to cataract surgery or other eye surgeries. The primary goal is to restore clear vision by using a specially prescribed corneal contact lens. The expected outcome is improved vision and better quality of life for the patient.

Indications

• Patients with aphakia in one eye.
• Individuals requiring vision correction post cataract surgery or lens removal.
• Patients seeking an alternative to eyeglasses.

Preparation

• No fasting or significant medication adjustments typically required.
• Comprehensive eye examination to measure eye curvature and visual acuity.
• Review medical history and current medications.

Procedure Description

1. Eye Examination: Comprehensive evaluation of the eye.
2. Lens Prescription: Measure the eye's shape and size to determine the appropriate contact lens power.
3. Lens Fitting: Apply the contact lens and assess its comfort, fit, and visual clarity. Adjust as necessary.
4. Adaptation Monitoring: Patient wears the lens under supervision to ensure proper adaptation and comfort.
5. Education: Instruction on contact lens care and hygiene.

Tools and equipment used include a slit lamp, keratometer, and specialized trial contact lenses. No anesthesia or sedation is typically required.

Duration

The fitting and initial prescription process typically take about 1 to 2 hours. Follow-up visits for adjustments may be required.

Setting

Performed in an ophthalmologist's office or an optometrist’s clinic.

Personnel

• Ophthalmologist or optometrist.
• Optician or trained assistant for lens fitting and education.

Risks and Complications

• Eye irritation or discomfort.
• Infection if proper hygiene is not maintained.
• Incorrect lens prescription needing further adjustments.
• Rare risks include corneal abrasions or ulcers.

Benefits

• Restoration of clear, binocular vision.
• Enhanced quality of life and daily functioning.
• Benefits are typically realized almost immediately after correct lens fitting and adaptation.

Recovery

• Follow-up appointments to monitor lens fit and eye health.
• Regular lens cleaning and proper hygiene practices.
• Advised to avoid sleeping with lenses or using them for extended periods initially.

Alternatives

• Prescription eyeglasses specifically designed for aphakia.
• Intraocular lens (IOL) implantation if suitable.
• Pros: Alternatives may provide consistent vision without the need for daily lens care.
• Cons: Eyeglasses may be less comfortable, and IOL surgery is more invasive.

Patient Experience

• During the procedure, the patient may feel mild discomfort or a sensation of foreign body presence.
• Post-procedure, some irritation may occur which usually resolves as adaptation progresses.
• Pain management includes lubricating eye drops and following care instructions diligently for comfort.
