Conventional-based contact lens fitting in pure microphthalmia associated with irregular cornea

BMJ Case Rep. 2022 Jul 7;15(7):e249534. doi: 10.1136/bcr-2022-249534.


In this case, a female teenager presented to the clinic with blurring of vision at a distance in both eyes since 2 years. All preliminary examinations were recorded. Retinoscopy revealed split reflex in both eyes. Both anterior and posterior segment findings seem to be within normal limits except for the microcornea. Topography depicts an asymmetric bow tie with superior steeping in both eyes. This case was diagnosed as pure microphthalmos associated with irregular corneal curvature, suggestive of keratoconus without corneal thinning with the help of topography and biometric measurements. Contact lens trial was advised to improve the visual potential. Fitting this patient in RGP lenses has been a challenging task because of narrow palpebral fissure height and small cornea.
