Muhtaseb et al developed a score which can help to identify a patient who may have problems during cataract surgery. The authors are from Moorfields Eye Hospital at St. George's Hospital in London.
Parameters:
(1) dense, total, white, brunescent cataract
(2) pseudoexfoliation
(3) phacodonesis (weak zonules)
(4) previous vitrectomy
(5) corneal scarring or cloudiness
(6) pupil size
(7) anterior chamber depth
(8) age of the patient
(9) ametropia
(10) posterior capsule plaque
(11) posterior polar cataract
(12) miscellaneous risk factors

where:
• A brunescent cataract is one with a brown or amber core.
total score =
= SUM(points for all 12 parameters)
Interpretation:
• minimum score: 0
• maximum score: 18 (or 17 if posterior polar cataract is not scored for a dense, total, white, brunescent cataract)
• The higher the score the greater the intraoperative risk for a complication.
