Abstract
Routine monitoring of preoperative, operative and postoperative data enables one to determine visual outcomes and assess quality of IOL surgery. Recent advancement in multifocal intraocular lens (MIOL) technology provides an increasing variety of choices to the ophthalmic surgeon and parameters to consider. It is well recognized that patients can experience different subjective responses to MIOLs with a small number of patients being dissatisfied with their quality of vision (QOV). Postoperative objective visual assessment is very important but it lacks insight into a patient’s subjective response to the intervention. Utilization of patient reported outcomes (PROs) is therefore essential to improve our understanding. Both standard (Rasch) and non standard methodologies are utilized to develop and analyze PROs in order to gain the greatest information from these valuable tools. Investigating pre or postoperative factors affecting the postoperative QOV enables the surgeon to stratify patients preoperatively with regards to those who would be more likely to complain postoperatively of substandard QOV. Stratification of patients suitable for MIOLs requires full ophthalmological assessment including refraction, unaided and best-corrected visual acuity, keratometry, topography, biometry, slit-lamp examination, Goldmann tonometry, dilated funduscopy and OCT. OPD-Scan, Topcon Aladdin, ARK-10000, Nidek Co., Ltd. and Adobe Photoshop suite are also used to ascertain aspects such as pupil size, angle kappa, pupil shift, capsulorhexis size and centration. Additionally, the position of asymmetric MIOLs is now recognized to represent an important consideration to optimize patients QOV.
