The objective clinical assessment of the quality of the anterior segment by means of the Oqual.
The Oqual is a simple new device attachable to the (Haag-Streit or Topcon) slit-lamp. It provides objective numerical assessments of the optical quality of the anterior segment. In the present study, patients attending Outpatients Clinics at Moorfields Eye Hospital were divided into those who suffered from lenticular symptoms and those who did not. Their monocular visual acuity was measured routinely by means of a Snellen chart, and thereafter their eyes were examined with the Oqual. Results are given for the correlation between the two measures overall (R2 = 47.35%), and for inter-observer performance (r = 0.8878). Earlier conclusions on the effects of smoking habits are supported.
