TLCT (Two Laser Combined Technique)
The TLCT is a technique which was invented in 2001 by the Team of the Surgical Polyambulatory of Modena (PCM), for the correction of all types of astigmatism, myopia (simple and compound) and mixed (associated to myopia or hyperopia), using two excimer lasers during the same operation.
The TLCT targets the smoothing of the corneal surface of the astigmatic eye, the cornea of which presents an abnormal curve with the consequential imperfect focusing on the retina at any distance.
Dr. Appiotti’s intuition on the use of two lasers arose from the idea of fully exploiting the characteristics of the two most advanced forms of excimer lasers.
Astigmatism is treated in two stages: the first laser treatment corrects the cylinder meridian of the defect by acting on the less curved meridian, making its curve more regular; the second laser treatment reshapes the surface to set a perfect focus of images, thus removing the residual visual defects.

The first stage is accomplished with a flying spot laser (VISX S4) which acts on the less refracting meridian on the peripheral part of the cornea; the second phase uses a 5 scan laser (NIDEK EC5000) to vaporize the central part of the corneal tissue to define the curve which perfectly corrects the visual defect.
This technique may be performed with both LASIK and PRK as the doctor sees best, after the pre-surgery assessment of the patient’s corneal topography.
At the end of the combined treatment in PRK a third “polishing” treatment (PTK smoothing) is performed through a NIDEK EC5000 laser’s regular and wide scanning passages with the help of a masking fluid, to eliminate all the mirco-irregularities of the combined action of the two lasers, creating a smooth surface. The actions of the two lasers are utilized during the same operation for each eye and both eyes can be treated during the session. The result is definitely better than the action of a sole excimer laser for the correction of simple and/or compound astigmatism, inasmuch as the final shape of the cornea (defined as aspheric) obtained is very similar to that of an eye that has not undergone surgery. This signifies a complete restoration of the patient’s vision which is always more than 10/10, with a better peripheral visual field of night vision (fundamental for equilibrium) and generally, with a sharper outline of images not even contact lenses and eyeglasses can obtain.

Dr. Appiotti applied an innovative TLCT technique on many sports professionals affected by astigmatism, obtaining a final vision of 10/10 with an overall improvement of the five fundamental elements (acute dynamic vision – quick glance perception – ocular movement – eye-hand/eye-foot coordination).This improvement of vision allowed them to improve their sportive performances.

Thanks to this unique and innovative technique (TLCT) which only surgeons of PCM perform, the correction of compound or simple astigmatism allowed all the sports professionals operated on to “train” all their visual capabilities, enhancing their visual “power”, their vigor, but also flexibility which led to excellent results, and reduced the number of accidents and trauma due to greater equilibrium and stability.
Thousands of operations have been performed with this technique since 2001, with a 0.15% of retreatments (i.e. surgery on possible residual defects).

Surgery procedure with the TLCT technique is as follows:
1. Anesthetic drops are placed in the patient’s eye.
2. The patient is made to lie down on a reclining bed under the laser instrument.
3. An eyelid speculum is placed to keep the eye open for the laser treatment;
4. The first laser treatment for astigmatism correction is performed.
5. The patient is made to sit up without eye pads or bandages and is positioned under the second laser instrument.
6. The second laser treatment is performed to complete the treatment.
At the end of the operation which lasts a few minutes, eye vision is temporarily blurred though the patient will already feel the change in vision which improves as the hours go by, without minimum pain or disturbing sensations.
After the treatment the patient stays in the waiting room for an hour and then is discharged. Post-surgery therapy consists in the administration of eye drops as indicated in the patient’s information sheet |
