Name of the Procedure:

Progressive Lens, per Lens (HCPCS Code: V2781) Common Names: No-line bifocals, Multifocal lenses Technical Terms: Progressive addition lenses (PALs)

Summary

Progressive lenses correct vision at different distances without visible lines on the lens. They provide a seamless transition from near to intermediate to far vision. This makes them a popular alternative to traditional bifocal or trifocal lenses.

Purpose

Progressive lenses help individuals with presbyopia, a condition where the eye's ability to focus on close objects decreases with age. The goal is to provide clear vision at multiple distances without the need for multiple pairs of glasses.

Indications

• Presbyopia
• Blurred vision at different distances (near, intermediate, and far)
• Patients who find it inconvenient to switch between different pairs of glasses for reading, computer work, and distance vision.

Preparation

• Eye Examination: A comprehensive eye exam is necessary to determine vision prescription.
• Frame Selection: Patients should select a comfortable frame that supports the progressive lens.
• No special preparations like fasting or medication adjustments are required.

Procedure Description

1. Eye Examination: The optometrist measures vision acuity and prescribes lenses based on the patient’s visual needs.
2. Lens Fitment:
   • Frame Selection: Patients choose a frame that suits their facial structure and personal preference.
   • Measurement: Precise measurements of the patient’s eyes and the frame positioning are taken.
3. Lens Fabrication: Based on the prescription and measurements, the lenses are crafted with a gradual change in lens power.
4. Lens Fitment: The progressive lenses are then fitted into the selected frame.

Duration

The entire process from examination to receiving the fitted glasses usually takes about 1-2 weeks. The fitting part of the procedure itself takes about 30 minutes.

Setting

The procedure is performed at an optometry clinic or an optical store.

Personnel

• Optometrist, who performs the eye examination and prescribes the lenses.
• Optical Technician, who assists in fitting and adjusting the frames.

Risks and Complications

• Adjustment Period: Mild dizziness or distortion can occur as patients adapt to the new lenses.
• Improper Fit: If the lenses are not properly fitted, it can cause discomfort and vision problems.
• Rare Complications: Instances of difficulty in adjusting to progressive lenses may require lens modification or alternative solutions.

Benefits

• Multifocal Vision: Single pair of glasses for near, intermediate, and distance vision.
• Cosmetic Appeal: No visible lines, unlike bifocals or trifocals.
• Convenience: Eliminates the need to switch between different glasses.

Recovery

• Adjustment Period: It may take a few days to two weeks for patients to fully adapt to progressive lenses.
• Follow-up: Patients are advised to follow up if they experience persistent discomfort or vision problems.

Alternatives

• Bifocal Lenses: Correct both near and distant vision but have a visible dividing line.
• Trifocal Lenses: Correct near, intermediate, and distant vision with visible lines.
• Contact Lenses: Multifocal contact lenses are also an option for some patients.
• Surgical Options: LASIK or other refractive surgeries might be considered for eligible candidates.

Patient Experience

Patients might initially experience mild discomfort or dizziness as they adapt to progressive lenses. Proper fitting and an adjustment period are essential for a comfortable experience. Opticians provide guidance on how to best use and care for the new lenses. Comfort measures like frequent breaks from reading or screen work, and gradual adaptation to wearing the glasses, can help ease the transition.
