Name of the Procedure:

• Specialty Bifocal (by report)
• Common names: Specialty Bifocal Glasses
• Technical/medical term: Bifocal Eyeglass Lenses, Custom Bifocals, HCPCS Code V2299

Summary

Specialty bifocal glasses contain lenses designed to correct both near and far vision for patients with presbyopia or other combined refractive errors. These custom-made bifocals are tailored to address unique visual requirements that standard bifocals may not adequately correct.

Purpose

Specialty bifocals address combined vision problems like presbyopia alongside other refractive errors such as myopia or hyperopia. The goals are to provide clear vision at multiple distances, improve quality of life, reduce dependence on multiple pairs of glasses, and minimize eye strain.

Indications

• Patients with presbyopia requiring near and far distance correction.
• Individuals with unique visual requirements or prescriptions not met by standard bifocals.
• Patients who experience discomfort or inadequate vision correction with off-the-shelf bifocals.

Preparation

• Ensure a comprehensive eye examination by an optometrist or ophthalmologist.
• Discuss visual needs and daily activities with the eye care provider.
• No specific fasting or medication adjustments are required.
• Existing eyeglasses prescription should be reviewed and updated if necessary.

Procedure Description

1. Eye Examination: A thorough eye exam to assess visual acuity and prescribe corrective lenses.
2. Customization: Measurements for the bifocals, including pupillary distance and segment height.
3. Lens Fabrication: Custom lenses are crafted based on the prescription and measurements.
4. Fitting: The patient tries the new bifocals, adjustments are made for optimal fit and comfort.
5. Follow-Up: Check-in to ensure vision clarity and comfort, and make any necessary adjustments.

Tools and equipment include ophthalmoscopes, phoropters, lensometers, and specialized software for lens customization. No anesthesia or sedation is involved.

Duration

• Initial eye exam: approximately 30-60 minutes.
• Lens fabrication: typically 1-2 weeks.
• Fitting session: around 30 minutes.

Setting

• Outpatient eye care clinic or optometry office.

Personnel

• Optometrist or ophthalmologist for examination and prescription.
• Optician for lens measurements and fitting.

Risks and Complications

• Initial discomfort or adaptation period.
• Potential for incorrect fit or prescription needing adjustments.
• In rare cases, persistent visual discomfort or headache.

Benefits

• Improved visual clarity for both near and distant tasks.
• Greater convenience with a single pair of glasses.
• Enhanced quality of life and reduced eye strain.

Recovery

• Immediate visual correction upon wearing the new lenses.
• Adaptation period of a few days to a couple of weeks.
• Follow-up visits may be needed to fine-tune the fit or prescription.
• No major physical restrictions post-procedure.

Alternatives

• Standard bifocals or multifocal lenses.
• Progressive lenses.
• Separate pairs of single vision glasses for near and far distances.
• Contact lenses designed for presbyopia.

Pros and Cons of Alternatives

• Standard bifocals: less costly but may not cover all visual needs.
• Progressive lenses: no visible line but adaptation may be harder.
• Multiple glasses: precise correction but less convenient.
• Contact lenses: cosmetic and practical benefits but require maintenance.

Patient Experience

Patients might initially feel some discomfort or disorientation while adjusting to their new lenses. The eye care provider will offer guidance on minimizing this and managing any minor discomfort. Regular follow-up ensures the glasses provide optimal vision and comfort. Pain is not typically an issue; however, mild strain or headaches can occur during the adaptation period.
