Life without glasses - LASIK or lens? Comparison of methods
In Germany, more than 60 percent of people over the age of 16 now need glasses - and the trend is rising. Extensive VDU work, long reading in rooms with little daylight and wrong eating habits have led to an increase in ametropia in recent years. However, many adults are bothered by the glasses and they opt for surgical measures such as laser eye surgery or lens implants in order to permanently dispense with the unloved "nose bike". An overview of which method is suitable and when:

LASIK - method of choice for low ametropia
Correction with the laser is considered very safe today. LASIK stands for laser-in-situ keratomileusis and is a scientifically recognized method to correct nearsightedness up to minus ten, farsightedness up to three and astigmatism up to approximately minus five diopters. In today's Femto-LASIK, a wafer-thin layer of the cornea is first prepared with a laser. This layer, also called a flap, is folded aside and the exposed inner surface of the cornea is treated with an excimer cold light laser. Dr. Robert Löblich, ophthalmologist at Artemis Eye Clinics in Frankfurt explains what happens: "The laser changes the refractive power in the eye and thus corrects the ametropia." LASIK has been approved in Germany since 1990 and is the most experienced procedure. The procedure is not suitable for pregnant women or nursing mothers, as changes in the refractive power occur in the body as a result of hormone changes. LASIK treatments are not or only partially suitable for people with rheumatism or certain eye diseases.

Contact lenses in the eye
In order to enable people with severe vision problems to live without glasses, doctors use artificial lenses that correct farsightedness up to eight diopters and nearsightedness down to minus 20 diopters - also in combination with astigmatism. In doing so, they put an artificial lens in addition to their own. The natural ability of the eye to focus itself at different distances remains the same with this procedure as with LASIK. A cut the size of a pin is sufficient for the procedure. "Since no tissue is removed here, lens implants are also suitable for people with very thin corneas," says Dr. Praiseworthy. "And the procedure is reversible." Stable glasses values ​​for at least one year are the basic prerequisite for the operation. In addition, doctors advise against such eye surgery for chronic eye infections as well as during pregnancy and lactation.

Extreme ametropia can also be eliminated
To treat extreme ametropia of up to -24 and +10 diopters, doctors use a combination of lens insert and LASIK. With all methods, patients enjoy their new eyesight shortly after the operation. "Many patients report that the operation gave them a completely new attitude towards life with an enormously improved quality of life," says Dr. (pm)
