Table 5 Criteria accomplished by the enhanced monofocals according to the ANSI standard definition of EDOF lenses and additional points

From: Positioning of enhanced monofocal intraocular lenses between conventional monofocal and extended depth of focus lenses: a scoping review

  1. RCT Randomized clinical trial, CS Case series
  2. ANSI-1: Statistical significance versus control for mean monocular visual acuity, with distance correction, at an intermediate distance of 66 cm
  3. ANSI-2: An increase in depth of field is achieved in the monocular defocus curve with distance correction equal to or greater than 0.5 D for a visual acuity level of 0.2 logMAR
  4. ANSI-3: The median monocular visual acuity, with distance correction, at an intermediate distance of 66 cm, is at least 0.2 logMAR
  5. ANSI-4: Monocular acuity at distance, with correction at this distance, is statistically non-inferior to control using a non-inferiority margin of 0.1 logMAR
  6. Add-1: Statistical significance versus control for mean binocular visual acuity, with distance correction, at an intermediate distance of 66 cm
  7. Add-2: An increase in depth of field is achieved in the binocular defocus curve with distance correction equal to or greater than 0.5 D for a visual acuity level of 0.2 logMAR
  8. Add-3: The mean monocular visual acuity, with distance correction, at an intermediate distance of 66 cm, is at least 0.2 logMAR
  9. Add-4: Starting with CDVA, the monocular defocus range at 0.2 logMAR is ≥ 1.5 and < 2.5
  10. Add-5: Starting with CDVA, the binocular defocus range at 0.2 logMAR is ≥ 2.0 and < 3.0
  11. Study limitation
  12. 1.- Lower sample size than described by ANSI
  13. 2.- Preoperative corneal astigmatism greater than that described by ANSI (1.0 D)
  14. 3.- Corneal incisions applied for astigmatism correction
  15. 4.- The evaluation intermediate distance is not 66 cm indicated by ANSI
  16. 5.- The chart used for testing visual acuity and defocus range is not the standard ETDRS or it has not been reported
  17. 6.- The chart used for testing intermediate visual acuity is not the standard ETDRS (i.e. Jaeger, Snellen, etc.) or it has not been reported
  18. 7.- The descriptive statistics is computed for a notation different of logMAR
  19. 8.- Control was not a standard monofocal
  20. 9.- Defocus curves were not measured with best distance correction
  21. Field color codes: Red (not accomplished), Green (accomplished), Yellow (unreported or unclear)
