Name of the Procedure:

Spherocylinder Lens Fitting, Bifocal, +/- 4.25 to +/- 7.00 Diopters (D) Sphere, 0.12 to 2.00D Cylinder
Common Names: Bifocal Glasses Fitting, High Prescription Bifocal Lens Adjustment
Technical Term: V2207 Spherocylinder Bifocal Lens Fitting

Summary

This procedure involves the fitting and adjustment of bifocal lenses for individuals requiring a significant prescription correction. It corrects both spherical and cylindrical vision issues within a specified range, helping the patient achieve clearer vision for both near and distant objects.

Purpose

The procedure corrects refractive errors such as myopia, hyperopia, and astigmatism in patients needing bifocal lenses. The goal is to provide clear vision at multiple distances, often improving the patient's overall quality of life by enhancing their visual acuity.

Indications

• Significant refractive errors including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
• Requirement for bifocal lenses due to presbyopia (age-related difficulty focusing on close objects).
• Prescriptions within the range of +/- 4.25 to +/- 7.00 diopters for sphere and 0.12 to 2.00 diopters for cylinder.

Preparation

• Patients should provide a current eye prescription.
• An eye exam might be required to ensure the prescription is up-to-date.
• No fasting or specific medication adjustments are typically necessary.

Procedure Description

1. Optometrist Consultation: The patient meets with an optometrist to discuss their vision needs and confirm the prescription.
2. Lens Selection: The appropriate spherocylinder lenses, based on the patient's prescription, are selected.
3. Frame Fitting: Frames are chosen and adjusted for optimal fit and comfort.
4. Lens Installation: Bifocal lenses are cut and inserted into the chosen frames.
5. Final Adjustments: The optometrist makes final adjustments to ensure a perfect fit.

Duration

The procedure typically takes 1-2 hours, including consultation, fitting, and adjustments.

Setting

The procedure is performed in an optometrist’s office or an optical shop.

Personnel

• Optometrist
• Optician

Risks and Complications

• Lens discomfort or improper fit
• Distortion or difficulty adjusting to bifocal vision
• Rarely, headaches or eye strain, which can be managed by further adjustments

Benefits

• Improved vision for both near and distant tasks
• Enhanced quality of life and ease in daily activities
• Benefits can typically be realized immediately after fitting and minor adjustments.

Recovery

• Post-fitting instructions may include tips for adjusting to bifocal lenses.
• Follow-up visits may be scheduled to ensure the lenses provide optimal vision correction.

Alternatives

• Single-vision glasses with separate pairs for near and distant vision
• Progressive lenses offering a gradual change in prescription power
• Contact lenses or surgical options like LASIK, where appropriate

Patient Experience

Patients might initially experience some discomfort or need time to adapt to the bifocal lenses. Pain is generally minimal, and optometrists can provide strategies to ease the transition. Regular wear should lead to better and clearer vision in both close-up and distant ranges.
