Study Arms (2)
Cacicol20
EXPERIMENTALInstillation of Cacicol20 eye drops after laser corneal surgery. 3 eye drops total, to be given once immediately after surgery, once 2 days after surgery, and a final time 4 days after surgery.
Placebo
PLACEBO COMPARATORInstillation of placebo eye drops (vehicle missing the active ingredient) after laser corneal surgery. 3 eye drops total, to be given once immediately after surgery, once 2 days after surgery, and a final time 4 days after surgery.
Interventions
Eligibility Criteria
You may qualify if:
- Signed and dated informed consent,
- Male or female aged ≥ 18 years,
- Patient with recurrent erosions or epithelial dystrophies indicated for treatment by phototherapeutic keratectomy of the anterior cornea
You may not qualify if:
- In the affected eye: prior corneal surgery
- In either eye: active ocular infection, glaucoma, or ocular hypertension
- General history judged by the investigator to be incompatible with the study (life-threatening patient condition).
- Known allergic hypersensitivity history to Poly(carboxyMethylGlucoseSulfate) or dextran.
- Inability of patient to understand the study procedures and thus inability to give informed consent.
- Participation in another clinical study within the last 3 months.
- Already included once in this study (can only be included for one treated eye)
- Known pregnancy (if uncertain pregnancy test will be performed)
- Lactation
- Women of childbearing potential without an effective method of contraception (oral contraceptive, intra-uterine device, subcutaneous contraceptive implant, vaginal ring) or women not hysterectomised, post-menopausal or surgically sterilized
