Cyclo refraction: This is a refraction done to get a more accurate measuement when the patient young (child) or is anxious focusing mechanism is working overtime. This relaxes the mechanism so the glasses measurement is accuracte.

See below: Cycloplegic refraction is generally performed with children and sometimes teenagers to determine their best spectacle correction. The use of special eyedrops helps to temporarily eliminate their ability to accomodate, thus giving a proper spectacle prescription. Seek out an eye doctor for more info and good luck!
A 44-year-old member asked:

What causes errors of refractions?

1 doctor answer1 doctor weighed in
Dr. Tim Conrad
Ophthalmology 34 years experience
Imperfect eyes: An error in refraction is imbalance between the amount of light-bending (refraction) an eye needs and what it has. A perfectly refracted eye bends the light the exact amount to focus on the retina. Most eyes are not perfect and need to lessen (in nearsightedness) or increase (in farsightedness) the amount of bending. This is done with glasses, contacts or surgery.

Can you tell me more about cycloplegic refraction (cyclo exam)?

Sure: this involves putting an eye drop in that paralyzes the ciliary muscle (the muscle in the eye that allows you to change focus). There are many reasons to do this and particularly in children in order to get the most accurate refraction. We usually don't do this in adults although sometimes it is necessary.
