NCT04178200

Brief Summary

It is aimed to determine patient satisfaction (pain assessment during and after the operation) and the initial and total anesthesia durations of eye lid and globe anesthesia after administration of local anesthetic solution only in standard applied volumes (1.5-3 ml). No agents will be added to the local anesthetic agents used in the conventional retrobulbar block in patients who will undergo cataract surgery,

Outcome Measures

Primary Outcomes (13)

  • Patient Pain Score

    patient pain assessed by with pain score of 3 points-scale (0 No pain,1 Not comfortable, 2 Have pain )

    Immediately after the surgery

  • The scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 1 minutes after the block

  • The scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 3 minutes after the block

  • The scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 5 minutes after the block

  • The scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 10 minutes after the block

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 30 minutes after the operation

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 60 minutes after the operation

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 90 minutes after the operation

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 120 minutes after the operation

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 150 minutes after the operation

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 180 minutes after the operation

  • The postoperative scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 210 minutes after the operation

  • The scores of ocular and eyelid movements

    Ocular movements will be scored separately for each direction, 2 if normal, 1 if slightly restricted and 0 if no movement. Complete inactivity will be scored as 0, partial movement as 1, and normal movement as 2 in the evaluation of eyelid movements.

    at 240 minutes after the operation

Secondary Outcomes (2)

  • The need for analgesic and how many times it needs

    One day after the surgery
