Abstract
Purpose: :
A retrospective chart review of patients who electively underwent cataract surgery in at least one eye performed by a single ophthalmologist with over 20 years experience in one of two outpatient surgery centers in Northeastern Oklahoma from January 2005 to December 2007. Stratification of preoperative risk factors for both increased TPET and/or increased APPEP was determined.
Methods: :
3120 patient charts and 6240 operative reports were reviewed. Data collected on these patients included age, ethnicity, sex, preoperative best-corrected visual acuity, cataract grade (nuclear sclerosis vs cortical spoking vs posterior subcapsular), lens thickness, first versus second eye, right versus left eye, birth month and insurance status. Other parameters included month and year the cataract was removed, which of the two surgery centers the operation took place, and whether a resident participated in the case.
Results: :
Mean TPET was 44.96 seconds (SD = 15.07) and correlated positively with patient age (mean = 72.70 years, SD = 9.47 years) (p value = 0.045). Mean APPEP was 18.84% (SD = 6.48%) and correlated positively with the cortical grading of the cataract (mean = 1.95/4, SD = 0.85/4) (p value = 0.001).
Conclusions: :
In our cohort of patients who electively underwent cataract surgery in at least one eye performed by a single ophthalmologist with over 20 years experience in one of two outpatient surgery centers in Northeastern Oklahoma from January 2005 to December 2007, increased TPET and APPEP was due in part to the cortical grading of their cataract and age, respectively.
