Name of the Procedure:

Fitting of Spectacle Mounted Low Vision Aid (Single Element System)

Summary

This procedure involves fitting a person with low vision with a special type of eyeglass that contains a single optical element to improve their vision. It's a non-invasive process where tailored lenses are mounted onto a spectacle frame.

Purpose

Medical Condition or Problem:

This procedure is designed for individuals with low vision, which means that even with regular glasses, contact lenses, medication, or surgery, their vision remains below standard.

Goals or Expected Outcomes:

• Enhance visual abilities for daily tasks such as reading, writing, and recognizing faces.
• Improve the overall quality of life by increasing independence.

Indications

Specific Symptoms or Conditions:

• Reduced visual acuity that cannot be corrected with standard eyeglasses.
• Conditions like macular degeneration, diabetic retinopathy, glaucoma, or other ocular diseases leading to low vision.

Patient Criteria:

• Patients who have been evaluated by an ophthalmologist or optometrist and have been recommended for low vision aids.
• Individuals with stable vision impairment.

Preparation

Pre-procedure Instructions:

• No specific dietary restrictions or fasting required.
• Continue any prescribed medications unless otherwise directed by the healthcare provider.
• Bring current eyewear and any previous eye examination records to the appointment.

Diagnostic Tests or Assessments:

• Comprehensive eye exam.
• Low vision assessment to determine the degree of impairment and the appropriate type of spectacle mounted low vision aid.

Procedure Description

1. Initial Consultation: The eye care specialist assesses the patient's vision and discusses their daily visual needs.
2. Measurement and Fitting: Accurate measurements are taken to ensure a perfect fit. This may involve trying different lens powers and configurations.
3. Customization: The selected lens is precisely ground and mounted onto the spectacle frame.
4. Final Adjustments and Training: The patient is instructed on how to use the new spectacles and may receive guidance on optimizing their use in daily activities.

Tools and Equipment:

• Specialized lenses.
• Spectacle frames.
• Measurement tools and fitting software.

Anesthesia or Sedation:

• None required.

Duration

The fitting process typically takes 1-2 hours, including consultation, measurement, and initial training.

Setting

The procedure is performed in an outpatient clinic, typically within an optometry or ophthalmology office.

Personnel

• Optometrist or ophthalmologist specializing in low vision.
• Optician may assist with lens fitting and adjustments.

Risks and Complications

Common Risks:
