At the Martínez de Carneros Ophthalmology Clinic we have a tried and tested refractive surgery department and we operate on and treat all the different cases using 100% laser techniques (more secure, precise and effective) as well as the implantation of intraocular lenses.




At the Martínez de Carneros Ophthalmology Clinic we have the innovative FEMTOSEGUNDO laser. This modern laser works with high precision infrared waves, which act in millionths of a second. This laser reproduces with great precision all the calculations and guidelines, consisting of microincisions, previously designed by the ophthalmologist surgeon, that correct the prescription of each patient.

This laser makes refractive microsurgery much safer, faster, more efficient and more accurate. As opposed to the more commonly used microkeratome that uses a blade to cut. This transfers heat to adjacent cells and also produces a mechanical cut in the corneal tissue, which consequently causes erosion of the corneal tissue and the results are worse.

Another of the great advantages of the FEMTOSEGUNDO laser against the microkeratome is its little invasive character, since it does not produce cuts in the tissues, if not the separation of them, placing the minimum dose of energy necessary for the disjunction of the cells.

The introduction of this laser in refractive surgery is a great improvement because the patient recovers a lot more quickly when we can perform surgeries in a more accurate, safe, effective and personalised manner.

One of the most common techniques used to treat and correct visual defects is FEMTOLASIK. This technique differs from “traditional LASIK” mainly due to the use of the FEMTOSEGUNDO laser instead of cutting with a microkeratome or blade. This means that the surgery is faster, safer, more effective, personalised and accurate.

After a thorough examination prior to surgery, in which we perform a variety of tests to know exactly what the characteristics of each eye are, both the surgeon and optician design a highly personalised surgery for each patient.

The surgical process is divided into two main steps:

  • Use of the FEMTOSECOND laser: applied on the corneal epithelium and with which we lift a thin layer of cornea (flap).
  • Use of the EXCIMER laser: with which we apply the treatment directly on the stroma, thus correcting the prescription.

After the application of this laser the corneal flap is replaced. The recovery time after this surgery is approximately 4/6 hours. During this time the patient may feel some discomfort but after several hours a full recovery and improved vision can be expected. Eye drops must also be used for a month.

After the previous and exhaustive study of each eye and the personalised design of each surgery, this treatment consists of the removal of the corneal epithelium (the outermost layer of the cornea). Once the epithelium has been removed, the EXCIMER laser treatment is applied to the stroma ablation and to correction the patient’s prescription.

The post-operative of this surgery is somewhat longer than in the case of FEMTOLASIK. The patient may experience discomfort up to 48/72 hours after surgery. In addition you have to apply eye drops for about 3 months.
