Update on Contact Lens Treatment of Keratoconus

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• Keratoconus (KC) is a progressive corneal disease impacting visual acuity and quality of life.
• Irregular astigmatism and corneal changes in KC necessitate specialized contact lens (CL) solutions.
• Patient tolerance and disease stage significantly influence CL selection for KC management.

Purpose of the Study:

• To review the current landscape of contact lens (CL) options for keratoconus (KC).
• To discuss advancements in CL materials and designs for correcting KC-induced visual impairments.
• To highlight the importance of specialized fitting methods for successful CL wear in KC patients.

Main Methods:

• Comprehensive literature review of scientific advances in keratoconus (KC) contact lens (CL) technology.
• Analysis of various CL types, including rigid gas permeable, soft, hybrid, and scleral lenses.
• Examination of custom CL designs and fitting methodologies.

Main Results:

• Significant technological progress has expanded the range of available CLs for KC.
• Specialized CL designs offer improved correction for irregular astigmatism.
• Patient-specific fitting and material selection are key to successful outcomes.

Conclusions:

• Contact lenses play a vital role in managing keratoconus, enhancing visual function and patient quality of life.
• The evolution of CL technology provides diverse and effective solutions for KC patients.
• Continued research into materials and designs promises further improvements in KC management.
