THE EVIDENCE BEHIND THE PULZAR PLATFORM

We don’t just describe our technology, we publish it. Below are the clinical studies and independent research this laser is built on, presented at international ophthalmology congresses and published in peer reviewed journals.

STUDY 1: MYOPIA, HYPEROPIA, AND PRESBYOPIA

Presented by Dr. Emanuel Rosen at the XXV Congress of the ESCRS.

Source: Binder SP. “Good results with the solid state laser, from myopia to presbyopia.” EuroTimes. 2008;13(4).

METRIC RESULT
Eyes studied 436 myopic, 195 hyperopic, 25 presbyopic
Myopia range Up to -14.5 D
Hyperopia range Up to +5.0 D
Predictability (myopic eyes) 98% within 1.0D of intended correction at one month
Presbyopia satisfaction 95.45% reported good bilateral near and far vision
Follow-up 1 to 3 months, across 8 international sites

At the same congress, Dr. Patrick Condon of Waterford, Ireland, who moderated the ESCRS Free Paper session, raised a common question about longer wavelengths: whether a faster laser might also mean a higher thermal effect on the eye. Dr. Rosen’s data answered this directly, showing no difference in thermal effect compared to the 193nm excimer wavelength, with speed as the only meaningful change.

Study 2: Myopia and Myopic Astigmatism

Presented by Dr. Gabriel E. Marin at the XXIV Congress of the ESCRS, with investigators Dr. Ioannis Pallikaris and Dr. Marc Tay.

Source: Guttman C. “Solid-state laser providing impressive outcomes in myopia and myopic astigmatism.” EuroTimes.

METRIC RESULT
Eyes studied 295, international, multicentre
Refraction range -0.5 D to -6.0 D, astigmatism up to -5.0 D
Within 1.0D of target 95% (against an FDA benchmark of 75%)
Within 0.5D of target 75% (against an FDA benchmark of 50%)
UCVA 20/40 or better 89% of treated eyes
Follow-up 100% follow-up to three months

Independent Wavelength Research

Dair GT, Ashman RA, Eikelboom RH, Reinholz F, van Saarloos PP. Absorption of 193- and
213-nm Laser Wavelengths in Sodium Chloride Solution and Balanced Salt Solution.
Arch Ophthalmol. 2001;119:533-537.

FINDING DETAIL
Penetration depth in balanced salt solution 20x longer at 213nm than 193nm
Penetration depth in 0.9% saline Approximately 1,600x longer at 213nm than 193nm
Clinical implication Reduced sensitivity to corneal hydration during surgery

What the Data Means in Practice

The Dair study above explains why our 213nm wavelength behaves differently on the eye than the 193nm excimer wavelength: it’s absorbed far less by fluid, which is why fluctuations in corneal hydration are unlikely to significantly affect ablation performance.

This same wavelength sits close to the absorption peak of corneal collagen, contributing to efficient, clean ablation with no evidence of thermal effect. Combined with our small spot size, homogeneous Gaussian beam profile, and high repetition rate, this is
the physical basis for the outcomes reported in the two studies above.
