Purpose.
To evaluate the difference in biomechanical properties between contact lens induced corneal warpage and normal and keratoconic eyes.
Method.
Prospective observational case control study, where 94 eyes of 47 warpage suspicious and 46 eyes of 23 keratoconic patients were included.
Warpage suspected cases were followed until a definite diagnosis was made (warpage, normal, or keratoconus).
Results.
44 eyes of 22 patients had contact lens related corneal warpage.
46 eyes of 23 people were diagnosed as nonwarpage normal eyes.
46 eyes of 23 known keratoconus patients were included for comparison.
The mean age of the participants was 23.8 ± 3.8 years, and 66.2% of the subjects were female.
The demographic and refractive data were not different between warpage and normal groups but were different in the keratoconus group.
The biomechanical properties (corneal hysteresis or CH and corneal resistance factor or CRF) were different with the highest value in the warpage group followed by normal and keratoconus groups.
CRF was 10.08 ± 1.75, 9.23 ± 1.22, and 7.38 ± 2.14 and CH was 10.21 ± 1.57, 9.59 ± 1.21, and 8.69 ± 2.34 in the warpage, normal, and keratoconus groups, respectively.
Conclusion.
Corneal biomechanics may be different in people who develop contact lens induced warpage.
