Outcome Measures

Primary Outcomes (3)

  • changes in post-operative outcome of pain

    by assessing the amount of pain on a visual analogue scale (score 0-9)

    day 1 postoperative

  • changes in post-operative outcome of redness

    scoring the amount of redness on a scale 0-4 through eye photos

    day 1 postoperative

  • changes in post-operative outcome in grading of anterior chamber cells

    clinical assessment by slit lamp examination (Tyndall 0-3 and Cells 0-3)

    day 1 postoperative

Secondary Outcomes (3)

  • visual acuity

    day 1 postoperative

  • intra-ocular pressure

    day 1 postoperative

  • pain-assessment

    1 week postoperative

Study Arms (2)

27 gauge needle vitrectomy surgery

ACTIVE COMPARATOR

ultra-small gauge

Device: vitrectomy (27G gauge or larger needle)

larger than 27 gauge (23G or 25G) needle vitrectomy surgery

ACTIVE COMPARATOR

23-gauge and 25-gauge instruments are a little larger in size

Device: vitrectomy (27G gauge or larger needle)

Interventions

vitrectomy surgery for either floater removal or macular surgery, with or without combined cataract (phaco) surgery.
