Purpose

To determine the change of corneal curvature following novel thermo-mechanical action based peri-orbital fractional skin treatment for the treatment of dry eye disease (DED) with reference to importance for  intraocular lens (IOL) calculation and refractive surgery.

Setting

A multicentre, prospective, controlled, open labelled study was conducted at Midland Eye, UK, Vallmedic Vision, Andorra and Khmer-Sight Foundation, Cambodia.

Methods

Consented participants attended visit-1, 2, 3, and 4 every two weeks and visit-5 for 3 months follow up. Participants received three sets of skin treatments for dry eye on visit-1, 2 and 3. Detailed ophthalmic examinations including vision, intraocular pressure (IOP), were conducted as well as corneal topography.

Results

One hundred and forty one participants (105 females; mean age 55.26±14.54years) with signs and symptoms of DED. This novel dry eye treatment was associated with no adverse events. DED as measured by OSDI questionnaires, tear break up time and tear osmolarity showed significant improvements in DED. Following cumulative analysis, a total of  3.5% of participants had more than 1 Dioptre change in mean keratometry (which results in more than 1D change in the power of the calculated IOL),  5.7% had more than 0.75 dioptres and 9.9%  had more than 0.50 dioptre change in keratometry following treatment.

Conclusion

Thermo-mechanical action based peri-orbital fractional skin can have a significant impact on corneal curvature measurement. It is vital to treat dry eye first before performing biometry or refractive surgery, if not, major refractive errors from measurement error may result.
