Cataract surgery

Phacoemulsification cataract surgery

Cataract surgery involves opening the anterior capsule of the lens and removing the cataract, that is the opacified lens, with an ultrasound probe (phacoemulsification). The surgical technique allows fragmentation of the lens and its aspiration through a micro incision from 1.5 mm to 3.0 mm. An artificial lens is then inserted into the eye through a micro-incision, which unfolds after being placed in the lens capsule. The procedure takes from 20 minutes to 30 minutes. One eye is operated on first, then the other eye or if necessary the surgery takes place two weeks later.

FEMTOsecond laser-assisted cataract surgery

Phacoemulsification is the conventional and standard technique for treating cataracts. For several years now, we have been offering cataract surgery in our practice using the latest method, i.e. cataract extraction with the assistance of the FEMTOsecond laser by Zimer LDV Z8®. This new method of opening of the lens, corneal incisions and fragmentation of an opaque lens by the FEMTOsecond laser allows to obtain even better outcomes. The use of the laser increases the precision of the and the safety of the surgical procedure. Probably in the near future, this method will become the standard of cataract treatment.

There are now different implants that can simultaneously correct different vision disorders. Find below the types of implants offered.

A standard spherical lens designed to restore vision at a certain distance and is completely reimbursed by your basic insurance.

A basic monofocal aspherical lens restores near vision or far vision by focusing the light on a single spot (far or near focus). It has the disadvantage of requiring, in the majority of cases, the wearing of glasses for reading (near vision) and while working on the computer (intermediate vision). It allows the perception of contrasts superior to the standard spherical implant, especially in low light conditions.

A toric lens recommended in the case of significant corneal astigmatism. This lens feature may be combined with basic spherical and aspherical lenses as well as within a premium lens.

Premium lens i.e. advanced multifocal or EDOF lens (pseudo progressive – extended depth of focus lens) allows you to be less dependent on glasses at virtually all distances. These lenses are recommended for patients who, following the cataract surgery, wish to remain independent of glasses during their daily activities. This type of lens is also offered to people who want to stop using glasses or contact lenses (i.e. patients with a cataract, with an initial cataract, or even people who do not have yet a cataract) and patients who are medically ineligible to laser corneal refractive surgery. Advanced implants are also an alternative for patients, who want to get rid of glasses but who cannot undergo corneal refractive laser surgery (the procedure is called by acronym CLE – clear lens exchange or RLE – refractive lens exchange) or in patients who are already presbyopic who want to get rid of glasses (the procedure is called by acronym PRELEX – presbyopic lens exchange).

Correction of astigmatism is also possible within above mentioned advanced lenses.

Note that the FEMTOsecond laser-assisted cataract / lens removal procedure optimizes the performance of all implants.

CAUTION

Significant, violent, excessive efforts are prohibited after surgery. The patient needs to stay calm for a few days after surgery.

The procedures are performed on an outpatient basis, under local anesthesia. The patient cannot drive right after the procedure and it is also recommended to come accompanied.
