Name of the Procedure:

• Common Names: Single Vision Lens Fitting with Spherocylinder
• Technical Terms: Spherocylinder, Single Vision, Plano to +4.00/-4.00 D Sphere, 2.12 to 4.00 D Cylinder (HCPCS Code V2104)

Summary

This procedure involves fitting a single vision lens with specific spherical and cylindrical lens powers to correct vision. These lenses are designed to correct both spherical and cylindrical refractive errors in the eye, commonly prescribed for conditions like nearsightedness, farsightedness, and astigmatism.

Purpose

The procedure aims to correct refractive errors:

• Medical Conditions Addressed: Myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
• Goals/Outcomes: Improved visual acuity and clarity, reduced eye strain, and enhanced overall quality of life by enabling better focus.

Indications

• Symptoms: Blurred or distorted vision, eye strain, difficulty reading or seeing distant objects clearly.
• Patient Criteria: Patients diagnosed with refractive errors within the specified range (+4.00 D to -4.00 D sphere and 2.12 to 4.00 D cylinder), identified through a comprehensive eye examination.

Preparation

• Pre-procedure Instructions: No fasting or medication adjustments required. Patients should bring any current glasses or contact lenses to their appointment.
• Diagnostic Tests: A thorough eye examination, including refraction assessment to determine the precise prescription needed.

Procedure Description

1. Eye Examination: An optometrist or ophthalmologist will perform a refraction test to measure the eye's refractive error.
2. Lens Selection: Based on the refraction results, lenses with the appropriate spherical and cylindrical corrections are selected.
3. Lens Fitting: The chosen lenses are fitted into a frame. The patient tries the glasses to ensure comfort and correct vision.
4. Final Adjustment: The fit of the glasses is adjusted as needed for optimal vision and comfort.
   • Tools and Equipment: Phoropter for refraction test, trial lenses, lensometer, and spectacle frames.
   • Anesthesia/Sedation: Not applicable.

Duration

• Typically takes about 30 to 60 minutes, including the eye examination and lens fitting process.

Setting

• The procedure is performed in an optometrist's or ophthalmologist's office.

Personnel

• Healthcare Professionals Involved: Optometrists or ophthalmologists, opticians who assist in lens fitting and adjustments.

Risks and Complications

• Common Risks: Mild discomfort or eye strain when adjusting to new prescription lenses.
• Rare Risks: Incorrect prescription, lens defects, or frame misalignment.

Benefits

• Expected Benefits: Substantially improved vision, reduced eye strain, enhanced daily functioning.
• Realization Time: Benefits are typically realized immediately after wearing the new lenses.

Recovery

• Post-procedure Care: Regular usage of the prescribed glasses.
• Recovery Time: Immediate; however, it may take a few days for the patient to fully adjust to the new prescription.
• Restrictions/Follow-up: Patients are usually scheduled for a follow-up visit to ensure the lenses are working effectively.

Alternatives

• Other Options: Contact lenses, other types of corrective eyewear, or refractive surgery (LASIK).
• Pros and Cons: Contact lenses offer a wider field of vision but require more maintenance. Refractive surgery offers a more permanent solution but involves higher risks and costs.

Patient Experience

• During the Procedure: Minimal discomfort; the most invasive part is the eye examination and trying on different lenses.
• Post-procedure: Initial period of adjustment to new lenses; any discomfort usually subsides within a few days.
• Pain Management: Pain is not typically an issue, but any minor discomfort can be managed with over-the-counter pain relief if necessary. Comfort measures include ensuring the proper fit of the glasses and providing instructions on how to adjust to the new prescription.

This brief overview should give patients a good understanding of what to expect with the fitting of single vision spherocylinder lenses.
