This type of lens is the most common of the three offered. These toric trifocal lenses are implanted through a small incision at the corneal edge (minimally invasive) and allow you to see clearly in the distance, near and in the middle distance. The special feature of the trifocal lens compared to other intraocular lenses is that it has three focal points and thus ensures optimum vision in the near and far range and also in an intermediate range. This average distance range to our eyes is about 60 to 80 cm and is relevant for computer work, reading price tags or visual contact in conversation situations.
The UV filter prevents damage to the eye and provides 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?
- Cataract is the most important field of application for trifocal lenses.
- Patients over the age of 40 who never want to use glasses again.
- Patients with astigmatism (also with high values).
- No more need for glasses, no matter at what distance.
- Cost savings compared to the costs that result with glasses
- Sharp vision, regardless of the eye disease
Properties of the lenses to be used:
The lenses to be used must first have the CE (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.
