LightLink-CXL is also equipped with a closed loop power output circuit and built in
power meter, maintaining a safer and precise output energy
4.
Continue administering 1 drop of Riboflavin every:
-
3 to 5 minutes until the end of the procedure (in STANDARD mode).
-
1.5 to 2 minutes until the end of the procedure (in INTERMIDIATE mode).
-
1 minute until the end of the procedure (in ACCELERATED mode).
-
0.5 to 1 minute until the end of the procedure (in RAPID mode).
5.
Make sure that during the UV-A light is well centered and in focus during
treatment.
NOTE:
The Riboflavin administration timer can be set on the LightLink-CXL system to
provide audible reminder and message prompting the user to administer it.
6.
The LightLink-CXL will automatically turn off its UV-A light irradiance at the end
of the preset irradiation (3-30 minute) treatment period.
Post Treatment
-
Immediate and follow on post treatment care requires;
-
Administration of antibiotic eye drops (usually one drop per treated eye).
-
Application of a bandage contact lens on the treated eye.
-
Antibiotic eye drops and Topical Steroids QID for 4 days (QID = 4 times a day).
-
Apply Analgesics as needed.
-
Follow up daily, remove the contact lens on day 4.
-
Fluorometholone eye drops QID for 1 month.
Side-Effects
Data from various studies on Corneal Cross-linking indicates the treatment as save,
effective and with no significant side effects recorded to date. The safety of crosslinking
to the intraocular structures has been also extensively evaluated indicating that the
Keratocytes are depleted to the 300μm level. These cells however regenerate by 6
months. The corneal endothelium, the crystalline lens, and the retina are preserved as
long as a minimum corneal thickness of 400μm is respected. The ultraviolet light dose is
designed to prevent damage to the corneal endothelium and other structures within the
eye. No cataracts have been attributed to this treatment in European trials.
Postoperatively, there is some light sensitivity and mild discomfort during the first week
but not unlike photorefractive keratectomy (PRK). Other consequences of the
procedure include an inability to wear contact lenses for several weeks after the
treatment. Also, corneal shape changes necessitate the refitting of contact lenses or
changes in spectacle correction. As with many treatments, there may also be long-term
risks that have not yet been identified. The increased corneal rigidity resulting from the
procedure may wear off over time and further periodic treatments may be required.
Data from clinical research indicates repeat corneal cross-linking procedure needs to be
performed every 7 years.
