Monofocal lenses are implanted through a small incision at the edge of the cornea (minimally invasive) and allow you to see clearly in the distance. These lenses, however, only correct this defective vision (short-sightedness) and can be calculated in such a way that after refractive lens replacement a certain distance can be seen sharply without glasses.
The UV filter prevents damage to the eye and is intended to provide additional protection for the retina against harmful influences. Above all, however, it also seems to achieve an improved sense of contrast in some situations (e.g. when driving a car).
Which patients choose this lens?
- Patients who only have problems with distant vision
- Patients over 40/45 years of age who cannot cope with the altered vision and yet do not yet take the overall step towards the trifocal lens.
- Patients with a smaller budget
- Patients with cataracts
- Monofocal lenses are spherical and may subjectively lead to poorer vision and low contrast at night.
- Monofocal lenses cannot be used to correct astigmatism and age-related sight defects.
- After refractive lens replacement with monofocal lenses, reading glasses are usually necessary, since the eye cannot adapt to both visual conditions (distance / proximity). If one wants to do without glasses completely, another lens model must be selected. (see Multifocal lenses and trifocal lenses).
Properties of the lenses to be used:
The lenses to be used must first have the CE certificate (European Standards Certificate). Its use is very common and reliable lenses should be selected, which are known good results. In addition, a special injector should be inserted into the eye through the 2 mm incision. (If the lens forms its own shape in the eye, the width should be 13 mm and the length 6 mm).
Surgical technique and anesthesia:
Lens implantation is a completely painless operation. Anaesthesia is performed using special eye drops. This type of anaesthesia is also known as topical anaesthesia. After the drops the phacoemilsification method (phaco – folklore laser – method) is applied.
Duration of surgery:
Approx. 10 min. It can be shorter or longer, depending on the patient.
Is there any pain during or after the operation?
The procedure is completely painless as the treatment is performed under anaesthesia. Even after the operation you will not feel any pain.
What is the postoperative process? How quickly can you resume your normal daily routine?
The patient’s treated eye is kept closed for one night. From the next day, 2 drops are administered 4 times a day, but the patient can immediately resume his normal daily routine, including bathing. The eyes, the operation underwent after other eye surgery can be seen well. Once both lenses have been implanted, the adjustment to the lens also becomes much easier.
