Contact lens fitting in high degree myopia

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• High myopia presents unique challenges for vision correction.
• Both spectacle lenses and contact lenses are used, each with specific advantages and disadvantages.

Purpose of the Study:

• To review the pros and cons of spectacle and contact lens correction for high myopia.
• To discuss aftercare issues and fitting guidelines for this patient group.

Main Methods:

• Literature review of spectacle and contact lens correction for high myopia.
• Analysis of fitting considerations, including lens type, power, and patient-specific factors.
• Discussion of potential complications and management strategies.

Main Results:

• Spectacle correction for high myopia can lead to significant aberrations and weight.
• Contact lenses offer improved cosmesis and visual field but pose risks of infection and hypoxia.
• Soft contact lenses for high myopia are thicker, increasing potential for discomfort and handling issues.
• Rigid gas permeable lenses offer excellent optics but may have a longer adaptation period.

Conclusions:

• Careful patient selection and fitting are crucial for successful contact lens wear in high myopia.
• Comprehensive aftercare and patient education are essential to minimize complications.
• Both spectacle and contact lens options require individualized management approaches for high myopia patients.
