Femto cataract as a new approach in surgery
Cataract surgery has become a very advanced technique to ensure quick and painless elimination of this widespread age-related disease. During the surgery, clouded lens is emulsified by ultrasound, removed from the eye and exchanged for the implant. However, technique development does not stop there. The purpose of cataract treatment is not only to eliminate the disease, but also to ensure maximum vision and quicker recovery. One possible way to achieve this is to ensure a very gentle intervention, maximum precision and customization of the procedure according to the specifics of each patient. To meet these requirements, femto laser assistance is used during ultrasound phacoemulsification.
Laser-assisted cataract treatment at Excimer
During cataract phacoemulsification, a surgeon uses a femtosecond laser tool in addition to the microsurgical system. This helps eliminate virtually all contact, i.e. scalpel and other mechanical tools, at the major stages of cataract phacoemulsification.
- Making corneal micro incisions using preset parameters calculated according to the patient data. Noncontact incisions close more quickly to eliminate the risk of postoperative astigmatism.
- Making a slot in the capsule where the implant will be located. The slot has an ideally round shape and located right at the center to facilitate implantation of premium grade intraocular lenses.
- Pre-fragmentation of the crystalline lens nucleus to minimize the effect of ultrasound and reduce recovery times.
Each femtosecond laser-assisted cataract surgery is unique. The laser system makes it possible to customize all parameters of the intervention to match them with individual visual specifics and control the procedure at all stages.
Femtosecond laser: principle of operation ▼
A femtosecond laser beam can be focused at any depth with the precision of several micrometers. At the same time, a microbubble layer is created to delaminate the tissues at the molecular level without heat generation and affecting adjacent tissues. The femtosecond laser is capable of positioning many bubbles alongside each other to create a required shape. In this way, the tissues are not cut, but delaminated.
Equipment at Excimer clinic
Excimer uses LenSx femtosecond laser system specifically designed by Alcon (USA) for femtolaser cataract treatment. LensX system has an in-built intraoperative optic coherence tomography (OCT) unit to calculate the intervention parameters on-the-fly in accordance with individual metrics of visual apparatus and visualize and control the status of internal eye structures during the surgery. The result is maximum precision and safety during intervention.
Femto-assisted cataract treatment is becoming more and more popular in the world’s leading eye clinics both with ophthalmic surgeons and with patients. LenSx system helped perform over 350 thousand surgeries in 50 countries, as a testimony of reliability and effect of laser-assisted cataract treatment.
Advantages of femto laser-assisted phacoemulsification:
- Gentle and virtually noncontact manipulations with the cornea and internal eye structures;
- quickest possible recovery;
- maximum visual performance;
- better visual performance if high-quality lenses are implanted;
- maximum precision and customization of intervention parameters.
Femto-assisted cataract surgery is the best ophthalmology has to offer in the field of cataract treatment. At Excimer, we invite you to enjoy the benefits of the most advanced techniques!
