Name of the Procedure:

Prism Correction, V2715

• Common name: Prism lens
• Medical term: Prism correction per lens

Summary

Prism correction involves adding a special optical element to eyeglasses to help correct double vision or other binocular vision disorders. This adjustment helps align the images seen by each eye so they can be fused into a single, clear picture.

Purpose

Prism correction is used to address various vision disorders:

• Strabismus (misalignment of the eyes)
• Diplopia (double vision)
• Certain types of headaches or eye strain related to binocular vision issues The main goal is to improve vision quality and reduce symptoms like double vision and eye strain.

Indications

Prism correction is typically indicated for patients with:

• Double vision (diplopia)
• Misaligned eyes (strabismus)
• Eye strain or fatigue due to binocular vision problems
• Certain neurological conditions affecting eye alignment Ideal candidates are those who experience these symptoms and have been evaluated by an eye care professional.

Preparation

• No significant preparation is usually required.
• An eye examination by an ophthalmologist or optometrist to assess vision and determine the correct prism power.
• The patient may need to bring their current glasses for adjustment or fitting.

Procedure Description

1. Examination: Comprehensive eye exam to measure vision, eye alignment, and determine the necessary prism correction.
2. Prescription: The eye care professional writes a prescription for prism lenses.
3. Lens Creation: Lenses are ground and fitted according to the prescription, integrating prism correction.
4. Fitting: The patient tries on the new glasses to ensure comfort and correct alignment.

Tools: Prism bars, lensometers, and other optical tools. Anesthesia: Typically not required, as this is a non-invasive procedure.

Duration

• The eye exam may take 30 minutes to an hour.
• Prism lenses are usually available within a few days to a week, depending on the lab processing time.

Setting

• The procedure is performed in an outpatient setting, such as an optometrist's or ophthalmologist's office.

Personnel

• Optometrist or ophthalmologist to conduct the examination and prescribe the lenses.
• Optical technician to fabricate and adjust the lenses.

Risks and Complications

• Temporary discomfort or adjustment period as the eyes adapt to the new lenses.
• Rare instances of persistent double vision or eye strain.
• In rare cases, prism lenses might not fully resolve the visual issues, necessitating further intervention.

Benefits

• Immediate improvement in vision clarity and alignment.
• Reduction in symptoms like double vision, eye strain, and headaches.
• The patient typically notices benefits within the first few days of wearing the new lenses.

Recovery

• Minimal to no recovery time.
• Patients may need a brief adjustment period to get accustomed to the new lenses, typically a few days.
• Follow-up appointments may be scheduled to ensure proper fit and functionality.

Alternatives

• Vision therapy exercises to improve eye alignment without lenses.
• Surgery in severe cases of strabismus.
• Use of standard corrective lenses (without prism) if suitable.
• Each alternative has its own benefits and limitations, often discussed with the eye care professional.

Patient Experience

• Most patients experience immediate relief from symptoms.
• Initially, there may be slight dizziness or discomfort as the eyes adjust.
• Regular appointments and follow-ups are essential for long-term success.
• Pain is typically not an issue, but comfort measures such as proper frame fitting can enhance the experience.
