Phakic lenses are intended for high diopter correction (above -10 and +6 diopters) in people aged 20 to 40 who are not usually candidates for laser diopter correction.
Phakic lenses are recommended for people with high diopters and / or thin corneas, as well as for people who, due to other criteria, are not candidates for laser diopter correction. The patient does not need to wear eye aids for clear vision.
The phakic lens is implanted in the front of the eye without removing the natural lens of the eye. It looks like a contact lens, but these lenses do not need special care. Once installed, they can only be removed if needed.
The patient does not feel them or see where they are placed.
People who may be candidates for implantation of phakic lenses are:
People with high diopters (above -10 and +6, such as -15 diopters, -20 diopters, etc.)
People who are not candidates for laser diopter correction, and are aged 20 to 40 years;
People who have a thin cornea;
People who have a healthy eye and do not have an additional eye condition such as cataracts, glaucoma, chronic eye infections, etc.
The examination for laser diopter correction checks whether the patient is a candidate for implantation of lenses.
The examination for lenses consists of:
The examination lasts from an hour to an hour and a half and consists of:
Completing a questionnaire about the patient’s general health;
Mandatory reading of general information about laser intervention;
Checking diopters, visual acuity and intraocular pressure;
Pentacam imaging (3D analysis of the eye is performed and is used to detect certain eye abnormalities for which no symptoms have yet appeared);
Dilation of the pupils with eye drops and objective diopters;
Consulting the team about anything that interests the patient.
Preparations for the examination are started by a nurse. The examination continues with the ophthalmologist and the optometrist.
Prior to the examination, it is very important for the patient to rest from wearing contact lenses for a period of time in order to “rest” the cornea of the eye from the lenses. To manifest the real cylinder, i.e. the shape of the cornea without the pressure from the lens.
If the patient wears soft contact lenses, it is necessary to rest for a minimum of three days. If the patient wears semi-hard or hard contact lenses then they need to rest from them for a minimum of 7 to 14 days before the examination. In the meantime they can wear glasses.
Preoperative preparation takes about 20 minutes. Patients with chronic diseases, depending on the therapy they receive, have special preparations for which they are informed on the day of the operation.
The preparation is started by the nurse, during which the vision, tone and refractive measurement are taken again.
The patient is then transferred to the preoperative block and a history is taken. Blood pressure and blood sugar are checked. Then, in consultation with the ophthalmologist, if necessary, additional diagnostics are made and the pupils are dilated.
Once the patient is fully prepared, they are admitted to the operating room.
The patient lies on the operating bed, where anesthetic drops are instilled. The operation can take about 20 minutes.
During the operation, a small incision is made in the front of the eye. The phakic lens is inserted through the incision and placed directly in front of or just behind the iris.
Operation with implanted lenses can be done on both eyes on the same day. During the operation, the patient is awake and communicative with the ophthalmologist and feels no pain.
Due to the advanced technology and design of intraocular lenses, the operation when performed by experienced surgeons is a successful, safe, fast and painless operation.
After the operation, the patient is taken to an apartment. About half an hour after the operation the patient is checked out of the hospital (one-day surgery) without bandages, except at the request of the patient.
The following day is the first follow up after the operation, while the next is for 7 days and after a month.
The patient is prescribed therapy (antibiotic / corticosteroid drops and ointment) and is obliged to use it according to the time period prescribed by the ophthalmologist.
Most patients already show improvement in vision the very next day. It is normal to feel discomfort in the operated eye, such as occasional tingling and scratching. The eye may be red and teary, there may be a feeling of blurring, a halo, as well as blurred vision and double vision. All these symptoms are normal and will gradually disappear.
Restrictions after surgery are temporary and do not last long and are always in accordance with the recommendation of the ophthalmologist.
For the first 3 days after surgery, the patient should avoid washing their face with plain water and rubbing their eyes, and for the first month, should avoid strenuous physical exertion (such as lifting heavy objects). It is especially important to use the prescribed therapy regularly and correctly.
Sports activities are usually allowed 2-3 weeks after the operation, depending on the patient’s age and the intensity of the exercises.
Medical staff are available 24/7 for any consultation required after the intervention.
The package includes: intervention with local anesthesia, preoperative preparation and three follow-ups.
There is an opportunity to pay in installments without interest and additional costs.
