Outcome Measures

Primary Outcomes (3)

  • Patient Satisfaction (CatPROM 5)

    Validated patient satisfaction questionnaire are used. Specially designed and validated conversion tables are used to convert raw scores from questionnaires to Rasch calibrated measures.

    6 weeks

  • Self-reported Health Outcome

    A validated self-reported health questionnaire is used where a descriptive and vertical Visual Analogue Scale (VAS) are used. The descriptive scale assesses 5 domains at three levels of difficulty (no / some / extreme problems). The VAS is used to to record patients' self-reported health on a scale from 0-100 (100/100 being excellent health, 0/100 being very poor health.

    6 weeks

  • Patient Reported Symptoms (Speed II questinnaire)

    A validated questionnaire is used with a grading system to grade severity of dry eye . symptoms. Score out of 28. Higher the score, the more significant the dry eye symptoms.

EXPERIMENTAL

Experimental arm receives lubricant eye-drops (phosphate-free, preservative-free lubricant eye drops containing 0.15% Sodium Hyaluronate with vitamins A and E (AEONTM Repair) to be administered four times a day for 6 weeks following cataract surgery (in addition to the usual post-operative topical medications of Chloramphenicol 0.5 % eye drops for 1 week and topical dexamethasone 0.1% eyedrops (Maxidex) four times a day for 4 weeks).

Drug: AEONTM RepairOther: Routine post-operative eye drops used.

Control Arm
