Comparison of 5% Hypertonic Saline Versus 3% Hypertonic Saline in Resolution of Post-operative Corneal Edema.

Muhammad Aamir Latif70 enrolled

Overview

There is a lack of data to determine the comparative advantages of 5% hypertonic saline and 3% hypertonic saline over the other. Hence, the current study was planned to determine their comparative effectiveness by comparing the change in means of central corneal thickness in the groups receiving 3% hypertonic saline and 5% hypertonic saline eyedrops developing post-phacoemulsification corneal edema.

Although corneal edema and the associated visual impairment after cataract surgery are temporary, it is still a reason for discomfort for the patient. It is therefore absolutely necessary that the patient be counselled regarding the risk of developing corneal edema after phacoemulsification. Several international studies have demonstrated the effectiveness of 5% hypertonic saline in improving visual acuity and reducing corneal thickness through clinical and pachymetric assessments. However, similar research has yet to be conducted in the Pakistani population. The findings of this study would add to the existing literature and also help clinicians to opt for the better choice of care in achieving patients' good outcomes.
