Refractive surgery is the restoration of diopter defect in the eye by surgical methods.
The purpose of these interventions is always to eliminate the need for glasses. Changing the diopter of the eye has been one of the ultimate goals of eye surgery field for decades. Recent research has already made it possible to reduce the reading difficulty resulting from the aging of the eye. This eliminates the need for reading glasses. This affects a large proportion of people over the age of 40-45, as the lens inside the eye ages in everyone and sooner or later it becomes necessary to use reading glasses.
There are several ways to eliminate the need for your reading glasses:
1.Laser intervention: The most common method is to correct the dominant eye for distance while the non-dominant eye to close vision.
This so-called monovision method for which different forms are known as micro monovision or Custom Q. These are essentially similar procedures, but only the technological implementations are different. A detailed description of the laser treatments can be found in the laser eye surgery menu. However, it is important to note that WaveLight technology has a feature, called Custom Q, that allows us to provide a wider depth of focus and therefore greater independence of reading glasses.
2. Eye lens replacement: During surgery, we replace your own aging eye lens inside an eye with an artificial lens implant.
Artificial lens implants to be placed inside the eye: Nowadays, in addition to laser excimer conversion of the cornea, the eye lens replacement surgery can also be a solution to diopter elimination.
By implanting both mono- and multifocal artificial lens implants, one can eliminate the need for glasses.
Multifocal artificial lenses
The design of the multifocal artificial lens is unique:
They improve vision at all distances – near, far and the transitional distances – and provide the greatest freedom available to patients, who can see well without glasses after this surgery.
The surgical technique is practically the same as for cataract removal, so it is routine surgery for an experienced doctor.
Cataract surgery is one of the safest, most effective, and most common surgical procedures in the world. This can be done on in an outpatient care, requires approximately a 10–15-minute intervention, after which the patient can drive and get to work in about 2-3 days. See cataract removal.
- After the operation, glasses are no longer needed, neither near nor far distance
- After implantation, cataracts will never develop again
- It permanently removes the existing cataract
- It also improves the anatomical situation of patients with narrow-angle glaucoma
- For patients with cataracts.
- For those over 40 who want to get rid of their reading glasses.
This condition is called presbyopia, in which the patient can no longer focus to a close distance (about 40 cm).
- If your eyes are unsuitable for laser vision correction.
When is your eye suitable for this implant?
- If you only have a diopter defect or cataract, otherwise your eyes are healthy
- If you haven't had cataract surgery yet
- If you do not have serious health problems
- Suitable also if you have undergone laser diopter correction treatment (PRK, LASIK, FEMTO-LASIK)
As in all situations, however, some compromises can be expected here:
- During evening driving, there may rarely be vision glare or halo effect.
This can occur if the pupil is wider than average. Most patients find this compromise acceptable but be sure to discuss this with our doctors who are experienced in implanting these lenses. At our clinic, we can also measure the size of the pupil in the dark with infrared light.
- Implants are only made at half a diopter, so in the worst case -0.5 to +0.5 diopters may remain after surgery (this is not seen by the patient in his or her vision).
- If the wound healing is scarred, had a cylindrical diopter defect or eye axis distortion before surgery, then approximately half a year after surgery, a laser treatment may be needed to improve your vision.
Your doctor will inform you during the medial suitability assessment test, if you need to expect a supplemental laser treatment.
