SUMMARY
The research of Muriel M. Schornack, O.D., involves the study of therapeutic applications for scleral lenses. Scleral lenses are large contact lenses that create tear-filled areas over the cornea. She explores the guidelines, indications, experiences and outcomes in people using scleral lenses for eye problems.
Additionally, Dr. Schornack researches the delivery of primary eye care, including assessment of refractive error, screening for ocular problems and management of chronic ocular disease.
Focus areas
- Descriptions of outcomes of scleral lens wear for management of corneal irregularity and ocular surface disease. Dr. Schornack published some of the earliest reports of the use of commercially available scleral lenses for people with severe eye diseases. Her research has led to an expansion of indications for which scleral lens therapy may be considered.
- Evaluation of prescription and management practices for scleral lenses. Dr. Schornack conducted multiple survey-based studies that explored prescription and management practices of eye care professionals throughout the world. These studies helped define consensus-based guidelines for the use of these devices.
- Anatomical and physiological impact of scleral lenses on structures and processes of the eye. Placement of a rigid contact lens on the surface of the eye may positively or negatively impact ocular tissue and physiological function. Dr. Schornack completed studies that examined the impact of scleral lens wear on intraocular pressure, conjunctival tissue and corneal health.
Significance to patient care
People with irregular corneas cannot achieve functional vision with regular glasses or contact lenses. Scleral lenses provide clear vision in these individuals, allowing many to delay or even avoid surgery. Scleral lenses also protect the ocular surface in people with diseases that cause tear film or blink dysfunction.
Dr. Schornack's research expands awareness of the benefits of scleral lens therapy to eye care professionals who treat people with conditions that can lead to ocular surface compromise.
