Who is DTK most suitable for?
What are the advantages of the DTK method?
- The cornea’s central area is untouched by the treatment
- Non-invasive treatment without cutting the corneal tissue
- Technically simple treatment
What is the essence of DTK?
 Diode laser thermokeratoplasty – DTK is a surgical laser treatment used for correcting lesser degrees of long-sightedness and high degrees of astigmatism. DTK is the analogue of conductive thermokeratoplasty, routinely used at Lexum since 1998.
The course of the DTK operation
In the course of the operation, the patient lies on a comfortable couch. The eye’s surface is made totally numb using anaesthetic drops. The surgeon applies laser energy to pre-determined points on the periphery of the cornea using a leaser pen. The number of points and their distance from the centre of the cornea determines their dioptric effect.
The diode laser brings about biomechanical changes to the periphery of the corneal tissue, which lead to increased bulging in the cornea’s central area. Increasing the curvature increases the eye’s refractive strength and replaces plus spectacle glass or contact lenses. Thus light rays converge on the point of sharpest vision and a sharp image of the observed object falls on the retina. The entire length of time for applying the laser energy is usually less than two minutes and DTK for one eye takes roughly five to ten minutes. With regards to the better efficiency and more stable results, we now prefer to offer the majority of long-sighted patients the LASIK method over DTK.
