  • Previous report analysed the corneal topography in pure microphthalmos and reported that 75% of eyes in the microphthalmia groups were of false keratoconus.
  • In this case, we discuss corneal topography in detail for pure microphthalmia and the challenges faced in fitting contact lenses.
  • First report to discuss the contact lens fitting in microphthalmos associated with keratoconus without corneal thinning.

A Case discussing contact lens fitting in microphthalmos associated with keratoconus without corneal thinning.

  • 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.

  • This case demonstrates that contact lenses can provide functional improvement in vision for some patients who have microphthalmia associated with irregular cornea.
  • Conventional fitting method is better than software-based fitting method when there is abnormal lid position and corneal size.
  • Software-based fitting method reduces the chair time of the patient, but it will not take tear film and lid characteristics into account.
