Clinical Outcome Forecast

Description

Returns an outcome forecast with 4 key performace indices (KPIs) for an individual patient (manifest refraction) and a planned treatment (laser, method, laser mode).

The 4 KPIs are:
- Enhancement rate (percentage of eyes that will require a re-treatment)
- Loss of CDVA (percentage of eyes that will loose 1 or more Snellen lines of corrected-visual acuity)
- SE within 0.5 of emmetropia (percentage of eyes with postoperative SE of 0.5 or less)
- UDVA 20/20 or better (percentage of eyes with uncorrected visual acuity of 20/20 or better)

Please note that extrem or rare conditions may not return a forecast due to a lack of reference data.

Background
The prediction of post-refractive laser surgery visual acuity and refractive outcomes is useful to assess the risks of the surgery and to prepare the patient for any undesired outcome and its consequences (used for informed consent). The outcome forecast algorithm analyses the results of similar treatments performed over the last 3 years from the very large reference database (400'000 cases). Each parameter influences the calculations.
