研究概览
简要总结
To evaluate the corneal biomechanical alterations in patients with keratoconus and pellucid marginal degeneration following the use of RGP and Rose K contact lenses. Data comparision would be taken with the CORVIS ST parameters like
CBI
SP A1
DA RATIO
IR
To monitor the changes in corneal stiffness and deformation amplitude after a 3 and 6 months of RGP and Rose K CL wear in both patient group.
To assess the difference in post lens wear changes in the corneal biomechanical properties between RGP and Rose K lenses.
To understand which lenses are the better option to maintain corneal integrity
