Name of the Procedure:

Contact Lens, Hydrophilic, Toric, or Prism Ballast (HCPCS Code V2521)

Summary

Hydrophilic toric or prism ballast contact lenses are specialized lenses designed to correct vision issues related to astigmatism, a condition where the cornea has an irregular shape, and other related visual impairments. Made from water-attracting materials, these lenses maintain a stable position in the eye to provide consistent vision correction.

Purpose

Medical Conditions

• Astigmatism
• Presbyopia
• Other refractive errors requiring toric or prism ballast lenses

Goals

• To improve visual acuity and comfort for individuals with specific refractive errors.
• To provide a stable and clear vision correction solution.

Indications

Symptoms

• Blurred or distorted vision
• Eye strain or discomfort
• Headaches associated with uncorrected vision

Patient Criteria

• Diagnosis of astigmatism or related refractive errors.
• Patients who are suitable candidates for contact lenses as per their optometrist or ophthalmologist's assessment.

Preparation

Pre-Procedure Instructions

• Obtain a prescription from an eye care professional.
• Ensure that the eyes are free from infection or irritation.
• Remove any existing contact lenses several hours before the fitting.

Diagnostic Tests

• Comprehensive eye examination.
• Corneal topography to map the surface curvature of the cornea.

Procedure Description

1. Eye Examination: A thorough examination of the eye to measure vision correction needs.
2. Lens Fitting: The optometrist will fit a trial lens and assess fit and comfort.
3. Vision Assessment: Vision is assessed with the trial lens to ensure it corrects the specific refractive error.
4. Lens Adjustment: Adjustments are made to ensure proper alignment and comfort.
5. Training: The patient is trained on how to insert, remove, and care for the lenses. ##### Tools and Equipment
   • Contact lens fitting kit
   • Slit lamp microscope
   • Keratometer or corneal topographer ##### Anesthesia or Sedation
   • Not applicable

Duration

Typically, the fitting takes around 30 minutes to an hour.

Setting

• Optometrist’s or ophthalmologist’s office.
• Vision care clinic.

Personnel

• Optometrist or ophthalmologist
• Trained optical assistant or technician

Risks and Complications

Common Risks

• Mild eye irritation
• Initial discomfort ##### Rare Risks
• Eye infection
• Corneal abrasion ##### Management
• Discontinue use and consult eye care professional if severe discomfort or infection occurs.

Benefits

Expected Benefits

• Improved vision accuracy.
• Enhanced comfort compared to other types of lenses. ##### Realization
• Typically immediately upon correct fitting and insertion.

Recovery

Post-Procedure Care

• Regular cleaning and storage of lenses as instructed.
• Follow-up appointments for periodic assessment. ##### Recovery Time
• Immediate adaptation period; a few days to get accustomed.

Alternatives

Other Treatment Options

• Regular spherical contact lenses
• Glasses
• Refractive surgery ##### Pros and Cons
• Glasses: Easier to use but may not correct vision as precisely.
• Refractive Surgery: Permanent correction but includes surgical risks.

Patient Experience

During the Procedure

• Little to no discomfort during examination and fitting. ##### After the Procedure
• Some initial adaptation period.
• Most experience improved vision soon after wearing the lenses.
• Mild discomfort or irritation as eyes adjust.

Pain management and comfort measures include using prescribed rewetting drops and following the eye care professional’s instructions for lens care and wear.
