Name of the Procedure:

Spherocylinder, Single Vision Lens Prescription Common Name(s): Single Vision Lenses, Eyeglasses Prescription Technical Term: Spherocylinder Lens Dispensing (HCPCS Code: V2105)

Summary

In simple terms, this procedure involves prescribing and dispensing single vision lenses that correct vision within a specific range of prescriptions. It's suitable for individuals with mild to moderate levels of farsightedness or nearsightedness combined with astigmatism (irregular curvature of the eye's lens or cornea).

Purpose

The procedure aims to correct refractive errors, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, improving the patient's overall vision clarity. The expected outcome is better visual acuity, coupled with enhanced quality of life and ease in performing daily tasks that require clear vision.

Indications

• Blurred or distorted vision
• Difficulty focusing on objects at various distances
• Eyestrain or headaches associated with uncorrected refractive errors
• Patient's prescription falls within the specified range: plano to plus or minus 4.00 diopters (D) sphere and 4.25 to 6.00 diopters (D) cylinder.

Preparation

• No special fasting or medication adjustments are necessary.
• Prior to the procedure, a comprehensive eye examination with refraction assessment is required to determine the exact prescription.

Procedure Description

1. Eye Exam: The optometrist performs a comprehensive eye exam, including refraction tests, to determine the exact prescription.
2. Lens Selection: Based on the prescription, single vision lenses are ordered within the specified range.
3. Fitting: The lenses are fitted into the eyeglass frames chosen by the patient.
4. Adjustment: Once the glasses are ready, the patient tries them on, and fine adjustments are made for comfort and optimal vision.

Tools and equipment include an autorefractor, phoropter, and trial lenses for determining the prescription. No anesthesia or sedation is involved.

Duration

The entire procedure, from eye exam to the final fitting of eyeglasses, typically takes a few days to a week, depending on the availability of the lenses and frames.

Setting

This procedure is performed in an optometrist's office or an eye clinic.

Personnel

• Optometrist: Conducts eye exams and prescribes lenses.
• Optician: Fits and adjusts the eyeglasses.
• Ophthalmic Technician: May assist with preliminary tests and patient education.

Risks and Complications

• Incorrect prescription leading to visual discomfort or headaches
• Need for follow-up adjustments
• Rarely, allergic reactions to frame materials

Benefits

• Clear, improved vision
• Reduction in eyestrain and headaches
• Immediate visual improvement once glasses are worn

Recovery

• No recovery time is needed.
• Patients might require a short adaptation period to get used to the new prescription.
• No specific restrictions; follow-up appointments may be scheduled if adjustments are needed.

Alternatives

• Contact lenses: Offer similar vision correction with the advantage of not having physical frames, but may require more maintenance.
• Refractive surgery: Permanent correction but involves surgical risks and costs.
• Progressive lenses or multifocal lenses: Alternative if correction for both distance and near vision is needed.

Patient Experience

During the eye exam, patients may experience slight discomfort from bright lights or the dilation of pupils. After receiving their new glasses, patients might feel immediate improvement in vision, though minor dizziness or disorientation can occur at first. Pain management is not typically necessary, but any discomfort usually subsides as the patient adapts to their new lenses.
