MAF-1217 is meant as the medical device which is to be effective in most forms of DED; therefore, it is expected that study patients benefit from study participation, and can reduce the signs and symptoms of surgery induced DED in patients undergoing cataract surgery, in a TID application pre-surgery.

This is a multicentre, pre-market, open label, randomized, prospective study exploring the performance of MAF-1217 when administered pre-surgery, in reducing the sign and symptoms of post-surgery DED in patients undergoing cataract surgery. Patients will be enrolled 2 weeks before Surgery (screening visit), will undergo cataract surgery (Day 0 - Baseline/Surgery), and then will be seen at week 1 and 2 after surgery.

Inclusion Criteria:

1. At least 18 years old patients, male and female

3. Normal to mild DED according to OSDI chart
4. Diagnosis of Cataract requiring surgery
5. Wishing to participate in the study and able to sign the ICF
6. Shirmer test > 15 mm /5'
7. No topic ophthalmic medication, including lubricating eyedrops administration for at least 4 days before screening visit.

Exclusion Criteria:

1. Neuropathic causes of dry eye (diabetes, long-standing contact lens wearing, previous ocular herpes infections)
2. Patients with diagnosis of Glaucoma
3. Functional and anatomic eyelid abnormalities,
4. Complicated cataract,
5. Suture affixing during surgery,
6. Use of artificial tears in the month preceding the study visit
7. Coexisting corneal diseases
8. Autoimmune diseases
9. Past or active cicatricial conjunctivitis
