Open door day

Refrakční Centrum Praha will have Open Door Day on Friday 13 October 2017, which is a unique opportunity for those who are thinking about undergoing laser eye surgery or intraocular surgery but still have not had enough courage and would now like to learn more about the methods of laser surgery.

RECOMMENDATION SONJA DÄNZER

To undergo laser surgery at Refrakcni Center in Prague has been one of the best decisions of my life. I had -3 dioptres on both eyes before the surgery and had been wearing contact lenses for many years, constantly having trouble with them because of dry eyes and irritations. So I decided to get examined at Refrakcni center, as prices were much more affordable than in Switzerland. As it turned out I was an excellent candidate for the laser surgery, so I decided to go for it. More

Intraoculare surgery

Correction of a dioptric defect by means of human lens replacement (clear lens extraction, prelex)

Another possibility to correct dioptric defects in patients over 45 who show the loss of accommodation and impaired re-focussing to near distances (presbyopia) or whose lenses become cloudy is to extract the natural human lens (CLE - Clear Lens Extraction) from an eye and replace it with an artificial lens. This procedure is particularly suitable in patients who have different dioptres for distance and near vision. Prior to the procedure, a special examination (biometry) is performed to determine the ideal dioptric power of an artificial lens to ensure that the patient will be satisfied with the dioptric result as much as possible. The Clinic has a wealth of experience with this method since the procedure corresponds to conventional cataract surgery. The procedure is performed under local anaesthesia using anaesthetic eye drops, the procedure may also be performed under general anaesthesia. The human lens is crushed and subsequently aspirated using an ultrasonic phacoemulsifying apparatus. What remains from the original lens is the capsule to which an artificial lens is inserted. Its optical power is chosen individually according to the dimensions of the patient’s eyes and the extent of the patient’s dioptric defect to correct the defect in distance vision and the patient will usually use weak reading glasses after the operation. Monovision is another possibility when the dioptric difference between both eyes is small. One eye will retain a minor defect in distance vision (about -1.5 dioptre) and will then see better to near distances. The surgery is performed through a tiny corneal incision with a width of about 2-3 millimetres so the wound does not need to be sutured. This makes the procedure practically painless, speeds up postoperative recovery significantly, and allows very fast improvement of vision. After the surgery the patient should observe a resting regimen and apply eye drops. The surgery of the other eye is usually carried out in a standard fashion in 1-2 weeks.

The PRELEX (Presbyopic Lens Exchange) technique is the hottest news for the patients in the presbyopic age group. It replaces the non-accommodating natural lens with an artificial multifocal lens.

Intraocular phakic lenses

In patients with a high dioptric defect or with an extremely thin cornea, the laser surgery may be a risk or may fail to correct the defect completely. Laser photoablation makes the cornea thinner (the more dioptres, the more tissue is removed). At the same time, it is necessary to maintain a certain thickness to ensure that the procedure will be safe. This is why the high dioptric defect and the thin cornea are incompatible. Similarly, patients with a higher dioptric defect and too broad pupils may develop unpleasant side light phenomena ("glare", "starbursting") as a result of laser operation. These patients can be offered an alternative solution based on phakic lens implantation. A phakic lens is an artificial lens which is inserted inside the eye while the natural lens is being maintained. The combination of the implanted phakic lens and the natural lens allows for the desirable adjustment of dioptres while the accommodation of the natural human lens (focussing) is being maintained. The implantation of a phakic lens is a more complicated procedure since it involves the very deep parts of the eye. Advanced implants are inserted into the eye through an opening of about 3 mm, which represents about one half of their actual size. They are made of advanced soft materials which enable the implants to be rolled up and folded over when being inserted into the eye. The implanted lens is usually fixed to the iris (i.e. the dominant colour section of the eye), or it rests on it. Another option is that the lens is implanted behind the iris mimicking the anterior surface of the natural lens. The procedure is preceded by the thorough examination of the eye including the measurement of the depth of the anterior eye chamber and by the examination of the corneal endothelium. The results of such examination help to decide whether the surgery is suitable in a particular patient and to select the lens according to the extent of a dioptric defect. Procedures are carried out at a specialized facility under local anaesthesia using anaesthetic eye drops, or the surgery can also be performed under general anaesthesia. After the surgery, the patient should observe a resting regimen and apply drops. The surgery on the other eye is performed in a standard manner in 1-2 weeks.



Intraocular refractive surgery is performed by Dr. Novák (Head Physician) in the specialized facility.
