Comparing nucleotomy techniques !!

Poster Details

First Author: S.Fazili INDIA

Co Author(s):                  

Abstract Details

Purpose:

Alcon Infinity overlay is used to understand and compare the phaco time , torsional time and ' Common Dissipated Energy ' used in different nucleotomy techniques with an Alcon Infinity Phacoemulsification Unit in 4 cases of Grade 4 cataract

Setting:

Fazili Eye Care Center Srinagar , Kashmir India .

Methods:

Four cases , similar in age and level maturity ( Grade 4 ) were operated by the author using an Infinity phacoemulsification unit with Ozil . The recordings were done with an overlay showing the phaco time , torsional time and Common Dissipated Energy.At the end of the surgery these parameters are compared , highlighting the characteristics of the Divide & Conquer , Stop & Chop , Direct Chop and Trench & Chop in the four performed Grade 4 cataract phacoemulsifications .

Results:

Comparison of ' Common Dissipated Energency ' suggests values Divide & Conquer 33.14 ,Trench & Chop 28, Stop & Chop 14.90 , Chop 10.25

Conclusions:

The relevance of this comparison of the nucleotomy techniques lies in other parameters being similar 1. Same Surgeon 2. Same Phacoemulsification Unit 3. Same Theatre 4. Same Grade Cataract . 5. similar slit lamp appearance on first post operative day . . The results document and correlate well with facts about nucleotomy techniques techniques already known . Chopping does away with the energy used in trenching , using mechanical manoeuvres to divide the nucleus .
