Autorefraction versus subjective refraction

 

The December 2005 issue of the Journal of Cataract and Refractive Surgery publishes a letter from Sandra M. Brown, MD of Concord, North Carolina, USA, commenting on the article published in Cataract Refract Surg 2004; 30:1921-1928, namely Autorefraction as an outcome measure of laser in situ keratomileusis. Her comments conclude with:

"Pesudovs has shown that Nidek autorefraction provides a reasonable starting point for subjective refraction after LASIK in myopes and low hyperopes. The retinoscope can serve this purpose, and it will also give the ophthalmologist a marvelous insight into the quality of the patientís corneal optics (being, in this regard, much cheaper than a wavefront analyzer)."

In his reply Konrad Pesudovs, PhD, states:

"Having established that autorefraction can be used as an outcome measure for laser refractive surgery, the philosophical question arises as to when it should be used. I agree with Brown that subjective refraction is the preferred methodology. However, there is subjective refraction and there is subjective refraction. As good as age-old methods of subjective refraction and retinoscopy may be, we should not stop the search for new and better methods. Science will show us what these are."
