PHAKIC LENSES FOR PERSONS WITH HIGH DIOPTERS AND THIN OR IRREGULAR CORNEA (IMPLANTABLE COLLAMER LENS (ICL), VERISYSE, VERIFLEX)

 

With people who have extremely high diopters (over -10.0 or +6.00) or if the eye examination reveals that their corneas (anterior transparent part of the eye) are too thin for laser action, or have some irregularities on cornea due to which laser vision correction would subject them to the risk of complications, there is a possibility of implanting the phakic lenses (ImplantableCollamerlens (ICL), Verisyse, Veriflex) in the eyes.  These lenses are implanted in the anterior part of the eye (in front of or behind the apple), without removing the natural lens and they function as contact lenses in the eye, with a difference that the patient does not have to take care of them nor can he/she feel them. The operation is done through small incisions that most frequently do not need to be stitched. The operation is almost completely free of any complications and is extremely non-invasive for all structures of the eye (none of the eye structures is removed). It is especially convenient for young persons who have not yet lost the possibility of accommodation, i.e. a possibility of the eye to adjust and sharpen the image both at near and far distance.  A person cannot feel that he/she has a lens in the eye, neither can the lens be seen by bare eye, while the lens is intended to remain in the eye for a lifetime.

 

There are a number of types of such lenses (ImplantableCollamerlens (ICL), Verisyse, Veriflex) that enable treating the spectrum of dipotres from -23 diopter to +21 diopter, as well as 6 cylinders of astigmatism. PSee the most frequently asked questions of the patients.

 

IMPLANTABLE COLLAMER LENS (ICL)   

 

Persons with high diopter that cannot be treated with a laser operation may proceed to implantation of a new type of phakic lenses, the so-called ICL (ImplantableCollamerLens). The ICL are currently considered the best quality solution for persons who are not good candidates for laser vision correction and they fall within the diopter spectrum from -3 to -20 and +0.50 to +10, they also correct astigmatism by up to 6 diopters. Compared to the other generations, phakic lenses have higher optics, and are also suitable for the persons with big diameter of the eye apple. Also, due to the position of the lens in the eye, these lenses have been noticed to significantly improve the visual acuity with the persons with big minus diopters, compared to the glasses and contact lenses

 

The patients suitable for the ICL are the persons between 20 and 50 years old, who have a stable diopter which is not suitable for laser operation due to the size of the diopter, thin cornea or eye diseases that are contraindicated for laser.  It is made of a biocompatible material and does not cause an immunological reaction of the eye, and also has a property of anti-reflexion and UV protection.

 

The lenses are implanted behind the iris (in the back eye chamber between the iris and the natural lens). The advantage of implanting the lens is in irreversibility of the operation, i.e. in case of a significant increase in diopter or development of the cataract, the lens can be taken out/replaced by another lens of appropriate diopter or another lens type without further damage of the eyes. See the most frequently asked questions of the patients.

 

MULTIFOCAL (TRIFOCAL) LENSES FOR DEALING WITH THE DIOPTER FOR NEAR DISTANCE AND FAR DISTANCE  

 

The persons after 40 years of age who wear both reading and distance glasses are the candidates, as well as persons who have developed the cataract. There is no upper age limit for implanting this type of lens. The only condition for a successful implantation and excellent result is the preserved health of macula.

 

The technology implies the replacement of natural lens with artificial lens with more diopters, which enables good vision at distance, up close and medium distance (necessary to work at the computer). The operation that lasts from 10-15 minutes is done in drop anaesthesia with a surgery of small incision which is only 2.2. mm big and does not require stitching. The patient can go home only a half hour after the operation, and the recovery lasts for only 2-3 days.   A trifocal lens of Company Carl Zeiss the design of which offers the vision quality most similar to a young eye and has a possibility of sharpening the image at all distances, is considered to be the most advanced implant in the market.

SPECIALIZED THERAPY METHODS OF LASER VISION CORRECTON – treatment of the scars and higher order aberrations

 

Apart from vision correction, the laser technology is also used to treat parts of scars and corneal dystrophy. The method most frequently used to treat such diseases is PTK (Phototherapeutic Keratectomy) which remodels the surface itself of the cornea (the front transparent part of the eye) in order to remove a part of blurring and reduce the irregularities that blur the vision. After the operation, the medicines of type Mitomicin are also frequently used to additionally improve clearing of the cornea and control healing in order to keep the desired result.

 

There are also different types of treatments that are guided by the corneal relief or the optic of the whole eye, although they are most frequently used with the persons who had some sort of eye operation about 10 or more years ago in order to additionally improve the results obtained by the then technology.

 

Also today, with the persons suffering from keratoconus it is possible to correct a part of irregularity by laser after which a crosslinking is usually done to stabilize the results and prevent further progression of the disease. Something that is presently more frequent with the persons with keratoconus is applying a crosslinking in order to stop the progression of the disease, and then, after a few months following the stabilization, the implantation of the phakic ImplantableCollamerLens (ICL) with an appropriate diopter size to fully remove or decrease the dependence of these persons on glasses and contact lenses.
