Abstract Details

Purpose:

To determine the prevalence of dry eye represented by hyperosmolar tear fluid in subjects presenting for cataract surgery and the variability of pre-surgical calculations in normal and hyperosmolar populations presenting for cataract surgery.

Setting:

Cataract service, University Hospital Ayr, Ayr, Scotland

Methods:

On going prospective study. 60 eyes of 30 patients who underwent osmolarity testing at presentation for cataract surgery. Both normal-osmolar cohort ( <308 mOsm/L) and hyperosmolar cohort( >316 mOsml/L) had two pre surgical biometry measurement peformed with an optical biometer .

Results:

Interim) Of the 60 eyes in the cohort. 13 were found to be hyperosmolar. The difference in the mean keratometry measurements between two sets of biometry measurements (performed 30 min apart) was 0.2 dioptres (SD +/- 0.05) in the normal osmolar group compared to a mean difference of 0.15 dioptres (SD +/- 0.02) in the hyperosmolar group.

Conclusions:

Hyperosmolar eyes have may more variations in the keratometry measurements during catarct surgery.
