Name of the Procedure:

Common Name(s): Bifocal lenses
Technical/Medical Term: Spherocylinder, bifocal, plus or minus 4.25 to plus or minus 7.00 diopters sphere, 2.12 to 4.00 diopters cylinder, per lens (HCPCS V2208)

Summary

This procedure involves the prescription and fitting of advanced bifocal lenses designed to correct significant refractive errors in patients with both nearsightedness or farsightedness combined with astigmatism.

Purpose

Medical Conditions:

• Severe nearsightedness (myopia) or farsightedness (hyperopia)
• Astigmatism

Goals/Outcomes:

• Improve clear and focused vision at different distances
• Enhance overall quality of life by reducing dependency on multiple pairs of glasses

Indications

Symptoms/Conditions:

• Difficulty seeing objects clearly at various distances
• Blurred vision caused by astigmatism
• Frequent headaches or eye strain while reading or doing close-up work

Patient Criteria:

• Patients with sphere corrections of +4.25 to +7.00 diopters or -4.25 to -7.00 diopters
• Cylinder corrections of 2.12 to 4.00 diopters

Preparation

Pre-Procedure Instructions:

• Undergo a comprehensive eye examination by an ophthalmologist or optometrist
• Ensure current eye prescription is up-to-date

Diagnostic Tests/Assessments:

• Visual acuity test
• Refraction assessment
• Measurement of corneal curvature and pupil size

Procedure Description

Step-by-Step Explanation:

1. Examination: Eye health and vision are thoroughly evaluated.
2. Prescription: The ophthalmologist or optometrist determines the precise lens power needed for both distance and near vision correction.
3. Lens Selection: Bifocal lenses with appropriate spherocylinder power are selected.
4. Fitting: Lenses are custom-fitted to the patient’s eyeglass frames ensuring optimal alignment and comfort.

Tools/Equipment:

• Phoropter for lens power determination
• Ophthalmoscope for eye health examination
• Lensometer to verify lens prescriptions

Anesthesia or Sedation:

• Not applicable

Duration

Typically takes around 30 minutes to 1 hour for the entire appointment, including the comprehensive eye exam and lens fitting.

Setting

Performed in an ophthalmologist's office or optometry clinic.

Personnel

• Ophthalmologist or Optometrist
• Optician (for lens fitting and frame selection)

Risks and Complications

Common Risks:

• Initial discomfort or difficulty adjusting to bifocals
• Minor headaches or dizziness during the adaptation period

Rare Risks:

• Incorrect lens prescription leading to persistent vision problems
• Allergic reactions to lens material

Management:

• Follow-up visits to adjust the prescription or frame fit if necessary

Benefits

• Provides clear vision at both near and far distances
• Reduces the need for separate reading glasses
• Improved visual comfort and reduced eye strain

Recovery

Post-Procedure Care:

• May involve a brief adaptation period during which eye strain or discomfort can occur
• Follow-up appointments to ensure correct lens fit and prescription

Expected Recovery Time:

• Most patients adjust within a few days to a couple of weeks

Restrictions or Follow-Up:

• Avoid driving or operating heavy machinery if vision feels unstable during adjustment period

Alternatives

Other Treatment Options:

• Progressives or multifocal lenses
• Separate pairs of glasses for distance and reading
• Contact lenses designed for astigmatism

Pros and Cons:

• Progressives: Offer a more gradual change in lens power but can be more expensive.
• Separate Glasses: Avoids issues with bifocal adjustment but requires carrying and switching between multiple pairs.
• Contact Lenses: Convenient but may not be suitable for all patients due to maintenance or comfort issues.

Patient Experience

During Procedure:

• Non-invasive, painless fitting process
• Minor discomfort during lens fitting

After Procedure:

• Initial period of adjustment where some discomfort or difficulty focusing may be experienced
• Vision stabilizes, leading to comfortable, clear sight across different distances

Pain Management:

• Generally unnecessary, but over-the-counter pain relievers can help if headaches occur during the adaptation period
• Recommendations for gradual usage to ease adjustment.
