Name of the Procedure:

Prescription of optical and physical characteristics of and fitting of contact lens, with medical supervision of adaptation; corneal lens, both eyes, except for aphakia (Contact Lens Fitting for Corneal Lenses).

Summary

This procedure involves prescribing and fitting contact lenses that sit on the cornea of both eyes, ensuring they suit the patient's vision needs and eye health. The process is medically supervised to ensure proper adaptation and comfort.

Purpose

This procedure addresses vision problems such as nearsightedness, farsightedness, astigmatism, and other refractive errors. The goal is to provide clear and comfortable vision correction.

Indications

• Blurred or distorted vision due to refractive errors.
• Patients seeking an alternative to glasses.
• Suitable for individuals without aphakia (absence of the eye's lens).

Preparation

• Comprehensive eye exam.
• Discussion of medical history and current medications.
• Avoid wearing contact lenses for a specified period before the fitting appointment.

Procedure Description

1. Initial assessment of eye health and vision needs.
2. Measurement of corneal curvature and pupil size.
3. Selection and trial of contact lenses.
4. Evaluation of lens fit and eye response.
5. Instructions on lens care and wear schedule.
6. Follow-up visits to monitor adaptation and make any necessary adjustments.

Must-haves:

• Keratometer and corneal topographer for measurements.
• Sample contact lenses for trial.
• Instructions on proper hygiene and lens maintenance.

Duration

The initial fitting session typically takes about 1 to 2 hours. Follow-up appointments may take around 30 minutes each.

Setting

This procedure is usually performed in an optometrist's or ophthalmologist's office.

Personnel

• Optometrist or ophthalmologist.
• Trained optician or contact lens technician.

Risks and Complications

• Discomfort or irritation.
• Infection if proper hygiene is not maintained.
• Dry eyes.
• Incorrect lens fit requiring adjustments.
• Rarely, corneal abrasion or ulcer.

Benefits

• Improved vision and quality of life.
• Freedom from glasses.
• Enhanced peripheral vision compared to glasses.

Recovery

• Adaptation period: a few days to weeks.
• Follow proper lens care and hygiene.
• Regular follow-up appointments to ensure optimal fit and vision.

Alternatives

• Prescription glasses.
• Laser vision correction (LASIK).
• Other types of contact lenses (e.g., soft lenses, toric lenses).

Patient Experience

• Initially, the patient may feel slight discomfort or foreign body sensation.
• Improvements in vision are typically noted immediately after proper fitting.
• Instructions provided for pain management and comfort measures, such as lubricating eye drops.
