Cyclorefraction

During your child’s appointment, the doctor may order cyclorefraction and eye drops will be administered.

This will not be painful but may tickle for a short while.

The purpose of the drops is to dilate the pupils and to accurately measure the refractive power of the eye, which is important in evaluating your child’s visual function. Dilating the pupils also allows for a complete view of the retina and optic nerve and for the doctor to check for any abnormalities inside the eye.

Please be aware of the following: 

  • 3 rounds of cycloplegic eye drops will be given and it will take up to 30 minutes.
  • After which, there will be a waiting time of 30 to 45 minutes for the pupils to be dilated before cyclorefraction can be done.
  • Once cyclorefraction is done, the child will wait for doctor’s consultation.
  • The effect of the cycloplegic eye drops will generally last for 4 to 8 hours, up to 24 hours.
  • Dilation of the pupils often causes near vision to be blurred and child may complain of sensitivity to light.
  • Once the effect of the cycloplegic eye drops have worn off, your child’s vision will return to normal.
