Contact Lens, Hydrophilic, Spherical, Per Lens (V2520)

Name of the Procedure:

Common names: Soft Contact Lens, Hydrophilic Contact Lens
Medical term: Contact Lens, Hydrophilic, Spherical

Summary

Soft contact lenses are medical devices worn directly on the cornea of the eye. These lenses are made from hydrophilic (water-attracting) materials that allow oxygen to pass through to the cornea, providing comfort and clarity for those with vision issues.

Purpose

Hydrophilic spherical contact lenses correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The primary goal is to improve visual acuity and provide a comfortable alternative to eyeglasses.

Indications

Patients experiencing:

• Blurry vision due to myopia, hyperopia, or astigmatism.
• Discomfort or inconvenience with eyeglasses.
• A desire for a wider field of vision without obstructions.

Preparation

• Comprehensive eye exam to determine prescription and eye health.
• Contact lens fitting to find the right size and type.
• Instructions on proper lens hygiene and handling.

Procedure Description

1. The optometrist performs a detailed eye examination and measures the curvature of the cornea.
2. A trial lens may be placed on the eye to verify the fit and comfort.
3. Patients receive training on how to insert, remove, and care for the lenses.
4. Prescription lenses are ordered based on the fitting and trial results.

Duration

The fitting and instruction session typically takes about 1-2 hours. The actual wearing of the lenses is ongoing as prescribed.

Setting

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

Personnel

• Optometrist or Ophthalmologist
• Optician (for lens fitting and training)
• Clinic staff (for patient coordination and support)

Risks and Complications

• Eye infections if lenses are not cleaned properly.
• Dry eyes or discomfort.
• Corneal ulcers or abrasions in rare cases.
• Allergic reactions to lens materials or cleaning solutions.

Benefits

• Improved vision without the need for eyeglasses.
• Enhanced peripheral vision.
• Greater freedom for physical activities.
• Comfort for extended wear (depending on lens type).

Recovery

• No significant recovery period is required.
• Regular follow-up appointments to monitor eye health and lens condition.
• Continual care and maintenance of lenses as advised.

Alternatives

• Eyeglasses: Lower risk of infection but can be inconvenient.
• Rigid gas permeable (RGP) lenses: Offer sharper vision but may be less comfortable initially.
• Refractive surgery (e.g., LASIK): Permanent correction but involves surgical risks.

Patient Experience

• Some initial discomfort or adjustment period when first using the lenses.
• Gradual improvement in comfort with proper use and care.
• Potential for dryness or irritation, mitigated by using appropriate eye drops and following hygiene guidelines.
