For some patients, an intraocular lens implant is a more suitable method of their eye disorder correction than laser surgery. The most frequent reason is either a high number of dioptres or thin cornea. The solution is the implantation of a so-called phakic intraocular lens, which is inserted into the eye during a painless operation carried out on an outpatient basis while the biological lens remains unaffected. A phakic intraocular lens is suitable for myopic as well as hypermetropic eyes, including possible combinations with astigmatism.
Principle of the phakic intraocular lens
The lens is designed in a manner that allows the phakic lens to work with the biological lens in front of which it is implanted. After surgery the patient has two lenses in their eye – the artificial phakic one and their own biological one. Optical parameters of the phakic lens are determined during a thorough preoperative examination. The lens is ordered directly from the manufacturer, i.e. it is made-to-measure for each patient. The short, outpatient surgery lasting about five minutes is performed with local anaesthesia applied by means of eye drops. The surgery is painless. During the surgery the eye is exposed to intense light. The surgery is executed on both eyes in one day.
Benefits of a phakic lens
Among the benefits is the possibility to correct even serious eye disorders where vision after surgery recovers very quickly and the quality of the resulting vision is very high. A phakic intraocular lens represents a safe and lasting solution, which is stable in the long run and which does not require any other follow-up care and does not mean any limitations in everyday life. If necessary, it is possible to remove the phakic lens from the eye or to replace it with another one without affecting the biological lens in any way.
