Cycloplegic Refraction

Cycloplegic Refraction

A refractive error could cause damage in the eyes in the long run, and so a cycloplegic refraction must take place. Cycloplegic refraction is done to determine complete refractive error in the eyes.

The normal refraction procedure always has a margin of error because of the patient’s influence. However, a Cycloplegic refraction is able to assess the full refractive error without the patient’s influence. Cycloplegic eye drops are used to temporarily paralyze the muscles that aid in focusing the eye.

There are three main types of patients that doctors perform Cycloplegic refraction on:

  • Children – Children tend to focus at a closer range than that of a farther distance, and so when a doctor performs this examination, they are confident they are measuring accurately.
  • Adults experiencing pre-presbyopia – Presbyopia normally occurs to people aged 40-45, it’s when we begin to lose ability to focus on objects nearby. This is why most people in that age group and above wear reading glasses or bifocal. In some cases though, people suffering from pre-presbyopia are having trouble transitioning their focus from near to far, and can become easily frustrated. This also causes night time driving symptoms. The best solution for these problems is to perform a cycloplegic refraction.
  • LASIK – People that have undergone laser vision correction or other refractive surgery should also undertake cycloplegic refraction to ensure that the accommodation doesn’t influence the results. Also, the surgeon must know how much of the vision problem must be corrected with laser.
