Name of the Procedure:

Single Lens Spectacle Mounted Low Vision Aids (V2610)

Summary

Single lens spectacle mounted low vision aids involve attaching a specialized lens to glasses to help individuals with severe vision impairment. These aids assist in improving the patient's ability to see by magnifying images or adjusting focal lengths.

Purpose

Single lens spectacle mounted low vision aids are designed to help individuals with significant vision loss due to conditions such as macular degeneration, glaucoma, diabetic retinopathy, or other eye diseases. The goal is to enhance the patient's functional vision, allowing them to perform daily tasks such as reading, recognizing faces, and navigating their environment more independently.

Indications

The procedure is indicated for patients who:

• Have significant vision loss that cannot be corrected with standard glasses, contacts, or surgery.
• Experience difficulty performing daily activities due to low vision.
• Have been evaluated by an eye care professional who has determined that low vision aids could benefit them.

Preparation

Preparation for this procedure typically involves:

• A comprehensive eye examination to assess the extent of vision loss.
• Discussions with an optometrist or ophthalmologist specializing in low vision to determine the most appropriate type of low vision aid.
• No specific dietary or fasting requirements.
• Adjustment of existing medications may not be necessary unless specified by the healthcare provider.

Procedure Description

1. Assessment: The patient undergoes a thorough eye examination.
2. Selection: The healthcare provider determines the appropriate type of low vision aid.
3. Fitting: The chosen lens is mounted onto the patient's spectacles.
4. Customization: The lens is adjusted to the correct position and focal length for optimal vision.
5. Instruction: The patient is given instructions on how to use the low vision aid effectively.

Tools and Equipment:

• Specialized spectacle frames.
• High-powered lenses or magnifiers.
• Measuring devices to ensure proper alignment.

Duration

The fitting and customization of the low vision aid typically takes about 30 minutes to 1 hour, depending on the complexity of the patient's vision needs.

Setting

This procedure is usually performed in an optometrist’s or ophthalmologist's office, or a specialized low vision clinic.

Personnel

• Optometrist or Ophthalmologist
• Low Vision Specialist

• Optician (for fitting and adjustments)

  Risks and Complications

  While generally safe, possible complications include:

• Eye strain or discomfort while adjusting to the new lenses.
• Temporary headaches due to changes in vision.
• Difficulty adapting to the use of the low vision aid, though this can often be managed with practice and follow-up adjustments.

Benefits

• Improved ability to see and perform daily activities.
• Enhanced independence and quality of life.
• Immediate vision improvement upon correct use of the aid.

Recovery

• Most patients can begin using their spectacle-mounted low vision aids immediately.
• Follow-up appointments may be necessary to adjust the lenses and ensure optimal functionality.
• Patients are usually advised to start using their new aids gradually to allow their eyes to adjust.

Alternatives

• Handheld magnifiers
• Stand magnifiers
• Electronic magnification systems
• Large print materials
• No treatment, though this may result in continued difficulty with vision-related tasks.

Each alternative has its own set of benefits and drawbacks. The choice often depends on the individual's specific vision needs, lifestyle, and personal preferences.

Patient Experience

Patients may experience a period of adjustment as they get used to their new lenses. Instructions and practice can help ease this transition. Pain or significant discomfort is uncommon, but any issues should be promptly discussed with the healthcare provider. Regular use typically leads to increased comfort and confidence in daily activities.
