Cataract is the most common disease affecting the elderly. It occurs in 70% of persons older than 75 years. It is a natural consequence of the aging process eventually leading to the blurring of the eye lens. In some cases, the initial cataract vision can be improved by glasses since the swelling of the lenses causes miopisation (minus diopter) in the eye, but with time and progression of the blurring of the lens the glasses can no longer be useful, and the only treatment option left is cataract surgery.
Manifested by blurred vision, loss of contrast and irritation in exposure to strong light. Affected patients may encounter amongst other symptoms also double vision, frequently problems with reading occur as well as with watching TV and driving. Cataract may be the result of a trauma, metabolic diseases (diabetes, galactosemia), administration of drugs (corticosteroids), but can also occur as a complication of other eye diseases (uveitis, glaucoma), as it can also occur as a result of certain syndromes (eg. Down’s syndrome).
To clear the blurring after cataract surgery, except for the removal of cataracts is necessary to incorporate an intraocular lens. The exact calculation of the diopter of the intraocular lens is essential for sharp postoperative vision, therefore we use the most modern computer device called “IOL Master” for the exact calculation of the strength of the lens.
At the Eye Clinic “Sistina Ophthalmology” you can do the same day both examination and intervention. The Cataract surgery is painless, fast, safe and effective after which you go back home with your eyes open. Thanks to state-of-the-art technology, the knowledge and experience of our surgeons, cataracts can be resolved within just 3 hours from your arrival at the clinic.
“Sistina Ophthalmology”, which is part of the Svjetlost group, has the biggest experience in implanting multi-focal – “Symfony” intraocular lenses that allow the patient to get rid of diopter and wearing glasses. With the built-in “Symfony” lens, the patient without glasses will be able to have good eyesight for near, middle and distance vision.
Monofocal and toric intraocular lenses
Monofocal intraocular lenses have one focus and enable to the patient good distance vision without glasses, however the patient will have to wear glasses for close vision (or vice versa, pursuant to patient’s wishes). If the patient before surgery had astigmatism (diopter error of the eye which is a result of incorrect curvature of the cornea), after surgery this patient will have to wear glasses both for distant and close vision with cylindrical lenses.
By incorporating toric lenses during surgery in patients with astigmatism good distance vision will be achieved, while for reading glasses will still be necessary. Monofocal lenses may be aspherical and spherical. Aspherical lenses corrected the so called spherical aberrations and give patients sharper vision in low light conditions, particularly in night driving and are suitable for physically very active patients.
Multifocal Intraocular Lenses
With the advances in technology there has also been a developement in the production of multifocal intraocular lenses which have 2 or 3 focuses and thus allow the patient good vision at different distances without glasses. Most multifocal lenses are bifocals. These lenses provide good distance vision and good near vision, but somewhat weaker vision at medium range distances (80-100 cm).
The latest generation of multifocal lenses are three focal lenses which not only provide the patients with good distance and near vision, but also a good vision at middle distances which is especially important for the patients who use the computer a lot. With the help of these lenses patients can without the need to wear glasses read newspapers and books, shave or do make-up, look at their devices, work on the computer, watch TV, drive a car, play sports and perform all the other daily activities.
