Abstract Details


To compare optical correction of presbyopia, contrast sensitivity and questionnaire of quality of life between a keratoconus' and a control presbyopic group.


: Clinic Saint Victor Ophthalmology, 354 Boulevard de Beauville, Amiens 80000, France.


This retrospective study compared 11 patients with no operated keratoconus (22 eyes) versus 10 control patients (20 eyes). We studied optical correction, contrast sensitivity, and the NEI-VFQ 25 questionnaire of quality of life. Results were tested with statistical analysis using the Mann Whitney test.


The average of near optical correction in the keratoconus group (K group) was 1.2 diopter+/- 0.5 vs 2.03+/-0.76 in the control group (p=0.009). Contrast sensitivity is lower in the K group. All scores of the NEI-VFQ 25 questionnaire of quality of life were globally significally lower in K group than in the control group.


This original study of presbyopia and keratoconus suggested that the physiopathogenesis of accommodation are not yet known. The results pointed that a probable corneal pseudo-accommodation could explain the persistence of the accommodation in the keratoconus group, as that seen after some refractive surgeries.
