To utilize quantitative “big data” analytics to characterize the demographics, visual outcomes, intraocular pressure changes, and patient satisfaction in a large cohort of refractive lens exchange patients in the United Kingdom.
A retrospective chart review was performed of an electronic medical record (EMR) containing over 12,000 cataract surgery visual outcomes combined with post-operative satisfaction surveys. Our study team obtained the mass IOL Master data (in a comma separated value format), downloaded Cirrus OCT data (in XML format), and downloaded the EMR data (in text format). Then we used a proprietary Python computer program written specifically for this study to match and merge the data into a single record based on medical record numbers. All data was anonymized prior to review by the study team. Statistical analysis was then performed using conventional statistical software.
Basic demographics of our population (n=12,419 eyes) demonstrated a median age of 57.0 +/-7.97 years, statistically insignificant female predominance of 51%, preoperative spherical equivalent of 1.50 +/-3.22 D, corneal curvature of 43.4 D +/-4.39, and intraocular pressure of 15.0 +/-3.18 mm Hg. Final spherical equivalent was close to emmetropia with median of 0.00 +/- 0.704 D overall, and similar in head to head comparison by lens type. No significant relationship between age, axial length, or intraocular pressure on final spherical equivalent in regression analysis. Final intraocular pressure after cataract surgery was decreased at 13.0+/-3.02 mmHg. Multifocal lenses demonstrated a predominance of younger patients across a number of manufacturers. Overall satisfaction after surgery was high for both monofocal and multifocal lenses, however satisfaction with near vision was greatest amongst multifocal lenses. All differences post-surgery were noted to be statistically significant (P<0.001).
Cataract surgery using either traditional or presbyopia correcting lenses was associated with excellent visual acuity, decreased intraocular pressure, and high surgical satisfaction. Multifocal lenses were associated with greater near visual acuity, similar decrease in intraocular pressure, and an increased frequency of complaints regarding glare/halos/ghosting around lights.
