Abstract Details

Purpose:

To report the outcomes of PRESBYOND Laser Blended Vision in commercial and military pilots with presbyopia requiring class 1 medical certification.

Setting:

London Vision Clinic, London, UK

Methods:

This was a retrospective study of 21 commercial and military pilots who underwent PRESBYOND Laser Blended Vision treatments using the MEL 90 excimer laser and VisuMax femtosecond laser (Carl Zeiss Meditec). Postoperative follow-up visits were conducted at 1 day, 1 month, 3 months and 12 months. Standard outcomes analysis was performed using the data at the last visit. A questionnaire of cockpit functional vision was given to each patient after surgery. At the time of analysis, 12 months follow-up was reached in 76% and 3 months in 24% of the patients.

Results:

Attempted SEQ was -0.22±2.41D (-4.00 to +4.88D). Cylinder was -0.65±0.52 D (0.00 to -2.75D). Binocular UDVA was 20/20 or better in 100% and 20/16 or better in 57%. Binocular UIVA was J3 in 79%, J5 in 89% and J10 in 100%. Binocular UNVA was J1 or better in 86% and J2 or better in 100%. Mean postop SEQ relative to target was -0.01±0.37D (-0.63 to +0.75D), 90% within ±0.50D. There was 1 line loss CDVA in 10%. Contrast sensitivity increased at 3, 6, 12, and 18 cpd. All patients achieved certification and reported improved cockpit functionality.

Conclusions:

Treatment by PRESBYOND Laser Blended Vision enabled presbyopic commercial pilots to continue to fly without the need for spectacles, even within the visually challenging environment of a cockpit where vision is required at near, intermediate, and far distance.
