EFFECTIVENESS OF PTechSIA QUESTIONNAIRE IN QUANTIFYING PHACOEMULSIFICATION SURGICAL TECHNIQUE VARIATIONS: A PILOT STUDY
Introduction: Detailed-documentation of phacoemulsification surgical techniques in operative note is not a routine in clinical practice. However, this information is crucial in order to quantify the variations in surgeonâ€™s surgical technique and to further evaluate the surgeonâ€™s surgically induced astigmatism (SIA) predictability. Aim: To assess the effectiveness of Phacoemulsification Technique Related to Surgically Induced Astigmatism (PTechSIA) questionnaire in quantifying the phacoemulsification surgical technique variations. Methods: Four ophthalmic surgeons (Surgeons A, B, C and D) at IIUM Eye Specialist Clinic were involved in this study. A validated self-administered questionnaire with 9 items (PTechSIA, patency number: LY2018002935) was employed to assess the surgeonsâ€™ surgical techniques during phacoemulsification. All the responds were scored for each item using Variation Score (VS). Score â€˜0â€™ was given, when a surgeon ticked only one option of the surgical techniques, Score â€˜1â€™ when a surgeon ticked two options, and so on for each item. VSs of all 9 items were summed up to obtain Total Variation Score (TVS). A higher TVS indicated a higher variation in surgical techniques. Results: PTechSIA showed that all surgeons had different TVS. Surgeons A and B had TVS of 1, whereas Surgeons C and D had TVS of 0 and 3, respectively. TVS of each surgeon indicated that all surgeons had variations in phacoemulsification surgical techniques. Conclusions: PTechSIA is an effective tool to evaluate and quantify the variation of surgeonsâ€™ surgical techniques in phacoemulsification. Hence, PTechSIA is suggested to be used extensively for a larger scale of surgeons in future research related to phacoemulsification surgical technique and SIA.
