Purpose

To demonstrate the effect on refractive status caused by two types of surgery for open angle glaucoma (OAG), Deep Sclerectomy (DS) and PreserFlo Microshunt (PMS)

Setting

This is an ongoing prospectively collected case series of patients undergoing DS and PMS surgeries in our glaucoma unit.

Methods

Pre-operative refractive status was collected using the autorefrator (ARK-1s NIDEK Autoref/Keratometer) and post-operative refraction was re-measured at 1 month post op, 3 month post op, 6 month post op and 12 month post op timepoints.

Results

A total of 21 eyes following DS and 20 eyes after PMS (mean age 35±89 years) with a diagnosis of mild to moderate OAG have been included so far (last update 29/02/24).  

The Astigmatism only changed post operatively at the one month mark, follwoing which there was hardly any change in the astigmatism in the previously included patients at each other time point and no statistically significant difference between groups. 

Conclusions

Both DS and PMS surgeries alter the refractive status of patients in the early post-operative stage but these changes resolve over the longer term (3 to 12 months) with no significant differences between DS and PMS surgeries.
