Conflicting conclusions from previous studies concerning the better option led the authors to design a single-centre, double masked, clinical study. Twenty-six subjects deemed to have ~ear film deficiency' were fitted with a low water content hydrogel lens on one eye and a high water content one on the other eye. Each subject wore the lenses on a daily wear basis (about 10 hours a day) for 30 days. A detailed questionnaire about subjective considerations, such as comfort and ocular appearance, was completed by the subjects at the end of every day of contact lens wear. The data obtained from these questionnaires and those recorded at three follow-up visits led to the final conclusions. The questionnaires showed no statistically significant difference between the two eyes in dryness sensation, redness, light sensitivity, blurred vision or overall comfort. During the follow-up visits, no observed sign showed a clinically significant difference between the two eyes.

To allow for statistical analysis, a thin lens was fitted in one eye and a thicker lens of the same characteristics in the contralateral eye. Subjects were asked to wear the lenses for 30 days on a normal daily wear basis and to graduate several factors such as comfort, dryness sensation, redness, photophobia, tearing, quality of vision and others. The results indicate that thicker lenses were preferred in terms of comfort, dryness sensation, photophobia and handling whereas thinner lenses were considered to give a better quality of vision. As a whole, thicker lenses were better tolerated by the patient. Central thickness was found to be of significant relevance when choosing a contact lens, especially when the tear film is deficient.
