简要总结
A post market clinical follow up prospective study to evaluate safety and performance of Eye Preparations (Carmellose Sodium Eye Drops).
Carmellose Sodium eye drops are used to relieve eye discomfort and soreness due to environmental factors. They moisten, soothe and lubricate the surface of the eye, making it feel more comfortable. Carboxymethylcellulose is a cellulose derivative that consists of the cellulose backbone made up of glucopyranose monomers and their hydroxyl groups bound to carboxymethyl groups. It’s viscous and mucoadhesive properties as well as its anionic charge allow prolonged retention time in the ocular surface. It exhibits protective actions on the ocular surface in various applications.
Polyhexamethylene biguanide binds to the negatively charged phospholipids found in the microbial plasma membranes causing membrane disruption and cellular lysis. Phosphate buffer (disodium hydrogen phosphate & Sodium dihydrogen phosphate dihydrate).Sodium phosphate, buffer, is the most physiologic of all the common buffers, as it’s a natural buffer occurring in tears.
Carmellose Sodium Eye Drops can be used to protect the eye from irritations/dryness/discomfort due to continuous use of computer/TV/exposed pollution/dry environment and use of contact lenses.
There will be 4 follow up visits expected after using the product:
1st Visit - After 8 days of using the product
2nd Visit - After one month of using the product
3rd Visit - After two months of using the product
4th Visit - After three months of using the product
| Intended purpose |
Persons who experience dryness, Itchiness, discomfort of eyes due to the continuous use of computer/TV/exposed pollution/dry environment use the eye drops to soothe the eyes.
|Intended users
Persons who experience dryness/itchiness/discomfort of eyes due to the continuous use of computer/TV/ exposed pollution /dry environment.
This study will be aprospective, multi-centric, non-randomized study. The subjects visiting thestudy centers with the complaints such as eye dryness, Itchiness, discomfort ofeyes due to the continuous use of computer/TV/exposed pollution/dry environmentwill be screened at Day 0 and if they meet the inclusion and exclusioncriteria, then they will be selected for the study. A total of 54 subjects will be recruited for this study for the Carmellose Sodium eye drops.

时间窗: 1st Visit - After 8 days of using the product | 2nd Visit - After one month of using the product | 3rd Visit - After two months of using the product | 4th Visit - After three months of using the product
次要结局
- The secondary objective is to assess any emerging undesirable events along with monitoring of desired events, contraindications, residual risk, emerging risk under normal usage of the eye drops for prolonged period to ensure acceptability of benefit risk ratio of the Eye drop, which will be recorded in CRF during every follow up visit based on the subject rating. The study will be focused on identifying possible systematic misuse or off-label use of the device.(1st Visit - After 8 days of using the product)
