Carl Zeiss VisuMax® + MEL™ 80

The laser system manufactured by Carl Zeiss has been used in our clinic since November 2008 and was upgraded in 2010 and 2012. At present it is the latest and most modern technology used for refractive corneal surgeries. The patient benefits from high comfort, safety and excellent preciseness. It employs the technologies of two different lasers. The femtosecond laser uses ultrashort pulses which are converged into a very small area where electron plasma is generated and micro-evaporation of the tissue takes place, generating a little bubble with an approximate diameter of 7μm. The pulses are aimed to be at a short distance from one another, which results in interconnection of the bubbles and creation of a very precise cut inside the corneal stroma. The other part of the VisuMax® Mel™ 80 system uses an excimer laser. After the corneal lamella (flap) has been pulled back, following a process of photoablation,  the excimer laser removes dioptres on the uncovered corneal stroma according to the predefined scheme tailored to the patient’s needs. VisuMax Mel 80 is used in our clinic to perform two types of refractive surgeries:

Laser surgery Femto Lasik

It is a laser eye surgery in which the eye is not in contact with any sharp instruments. The thin lamella is created by the femtosecond laser and after it has been pulled back, the excimer laser (Mel 80) rectifies the refractive error and the lamella is placed back in the cornea.

3D laser surgery ReLEx® smile

It is the most modern technology of refractive laser surgeries and constitutes a considerable step leading to minimally invasive surgeries.  Laser surgery is faster and the entire process is carried out in one step. Using the femtosecond laser, a lenticule is created deep in the cornea in 3D mode and is subsequently removed through a small incision.  As such  integrity of the surface of the cornea and the Bowman’s membrane is minimally disrupted. There is no need to use the excimer laser to remove dioptres. The method is limited by the type of refractive error – it cannot be used for long-sightedness, very low dioptres or too high or simple astigmatism.

 

Abbot IntraLase™ + VISX™ technology

Our clinic has been using the laser system manufactured by Abbott (iFS™ Advanced Femtosecond Laser + STAR S4 IR™ Excimer Laser) since December 2010. It is the 5th laser generation that has also gained the trust of the US Army and NASA. It is a very sophisticated and safe technology used worldwide. Just like Visumax Mel 80, it combines the technology of femtosecond and excimer lasers. We use IntraLase-VISX to perform Femto LASIK surgery. It is a laser eye surgery in which the eye does not come into contact with any sharp instruments. The thin surface lamella called a flap is created painlessly by the femtosecond laser. The other (excimer) laser subsequently removes the dioptres.

 

Alcon LenSx®

A brand new top-class surgical technology for cataract surgeries and refractive intraocular surgeries is presented by the femtosecond laser LenSx® manufactured by Alcon. As  the first femtosecond laser to be used for cataract surgeries, this laser was the first to obtain FDA approval for surgeries in the USA as well as the European CE certificate. No scalpel is used in laser surgery; all cuts are performed by a computer-controlled femtosecond laser beam. This method is much more precise than manual cutting with a knife or needle. The device comprises integrated OCT which displays the anterior segment for precise planning of the location, direction and depth of cuts.  Surgery is strictly tailored to the needs of each individual eye. The laser makes it possible to open the front lens capsule and fragment the lens, as well as to make primary and secondary incisions in the cornea through which instruments enter inside the eye and through which the intraocular lens is implanted. If required, it also allows for any pre-existing astigmatism to be corrected by means of arcuate incisions in the cornea. Exact planning and computer navigation leads to high precision and safety. Partial fragmentation of the lens considerably shortens the phacoemulsification time required for removing the lens, which also significantly reduces the amount of harmful energy entering the eye structures, thus also reducing the amount of related complications. The top-class technology is appreciated by both cataract patients and clients who undertake refractive lens exchange and implantation of a premium multifocal lens. Only a few clinics in Europe have this laser device. The surgery is not covered by health insurance meaning that the patient bears the costs.

 

Alcon CONSTELLATION® Vision System

The Eye Clinic Horní Počernice was the first clinic in the Czech Republic to buy the new device manufactured by the Alcon – CONSTELLATION® Vision System. This unique system combines a top-class phacoemulsification device for anterior segment surgeries (cataract surgeries and refractive intraocular surgeries) with the most modern equipment for surgeries of the posterior segment, i.e. vitreous body and retina. The device has been used in our clinic by cataract and retina surgeons since 1 September 2009. Phacoemulsification is currently the preferred method in cataract extraction. We use ultrasound energy to fragment lens material which is also suctioned by the system. All is done with small instruments entering the eye through small incisions in the cornea. With modern surgical instruments and systems, cataract surgery has become much less invasive than ever before.
