Changes in Vitreous Temperature During Phacoemulsification
Temperature in the vitreous cavity decreases during vitrectomy, and the same effect is seen during an uneventful phaco surgery. Significant changes occur between the baseline temperature and after every step of the surgery.
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Basic Science
|Official Title:||Changes in Vitreous Temperature During Phacoemulsification|
- Vitreous temperature [ Time Frame: Every five minutes during a phacoemulsification procedure, and at every step of the surgery ] [ Designated as safety issue: No ]Temperature of the vitreous is taken every five minutes from the start of a phacoemulsification. Also Temperature is take after every step of the surgery (capsulorhexis, hydrodissection, phacoemulsification, irrigation/aspiration, IOL implantation).

|Estimated Primary Completion Date:||March 2012 (Final data collection date for primary outcome measure)|
Determination of vitreous temperature with a thermoprobe
Transurgical measurement of temperature
Other Name: Thermoprobe
A 23-gauge thermometer probe inserted prior to the beginning of the cataract surgery to measure the vitreous temperature at different stages of the procedure (capsulorrhexis, hydrodissection, phacomulsification, irrigation/aspiration and intraocular lens (IOL) implantation). Room temperature also registered during every step. At the end of the surgery, oral temperature will be measured.
