Introduction

Callisto Eye – Precise adjustment in every surgical step
Phakic ICL – The Foundation of Phakic Pro
Phakic ICL (Implantable Collamer Lens) is an intraocular lens certified by the U.S. FDA and CE in Europe. It is placed behind the iris and in front of the natural lens to correct myopia and astigmatism without reshaping the cornea.
- Corrects myopia from –3.0D to –20.0D and astigmatism from 1.0D to 4.0D.
- Over 99% of patients achieve 20/40 vision or better postoperatively, with more than 90% reaching 20/20.
- Does not cause dry eye, making it suitable for patients with thin corneas, high myopia, or those who failed LASIK/SMILE.
- Removable if necessary, providing treatment flexibility.
A key feature of the new generation Phakic ICL is its AquaPort central hole design, eliminating the need for peripheral iridotomy, enhancing safety, and reducing surgical time.
CALLISTO® EYE & Artevo 750 – Precision to the Micron

Phakic Pro – Pioneering advanced refractive technology
Phakic Pro is not only based on the ICL platform but also integrates CALLISTO® EYE into the Artevo 750 digital surgical microscope. This technology projects axis, center, and incision location directly in the surgeon’s view, completely eliminating errors from manual marking.
According to clinical reports, accurate axis alignment improves postoperative visual outcomes by over 40% compared to traditional methods. This is critical in astigmatism correction, where even a 5-degree misalignment can reduce effectiveness by 15%.
Why Phakic Pro is a Breakthrough
1) Absolute Personalization
With IOLMaster 700, surgeons collect detailed biometric data including axial length, corneal curvature (K), white-to-white (WTW), anterior chamber depth (ACD), and pupil size. Anterior segment OCT provides additional mapping of the iris and chamber angle, along with vault estimation for lens placement.
From this data, a personalized surgical plan is created for each eye: selecting the right ICL size and power, aligning the astigmatism axis, and optimizing incision location – ensuring biological compatibility, safety, and maximum refractive accuracy.
2) Absolute Precision
CALLISTO® EYE overlays reference lines (axis, optical center, incision site) directly into the surgical microscope view as an augmented reality guide.
The system synchronizes with preoperative measurements and compensates for cyclotorsion when the patient lies on the surgical table, eliminating errors from manual ink markings. Surgeons simply follow the real-time guidance, placing the lens exactly where planned.
3) Faster and Safer
The seamless workflow – from measurement to planning to guided intraoperative display – reduces redundant checks and manual adjustments, significantly shortening surgical time.
A small corneal incision (a few millimeters) combined with minimally invasive manipulation reduces endothelial stress, stabilizes the anterior chamber, and speeds recovery. Shorter intervention time also lowers infection risk and enhances patient comfort during and after surgery.
4) Optimal Vision After Surgery
When the astigmatism axis is precisely aligned from the start, residual astigmatism is minimal, enabling early uncorrected visual acuity (UCVA) improvement and more stable quality of vision, especially under low-light conditions. Proper alignment also helps reduce glare and halos at night – common issues when residual astigmatism or misalignment persists.
Some patients may experience a short adaptation period before achieving optimal nighttime visual comfort.
Who is a Suitable Candidate?
- Patients aged 21–45 with myopia from –3.0D to –20.0D.
- Astigmatism from 1.0D to 4.0D.
- Thin corneas, dry eyes, or those previously deemed unsuitable for LASIK/SMILE.
- Individuals seeking quick recovery, safety, and clear vision immediately after surgery.
