Table 4.

Best corrected visual acuity (BCVA) in relation to the lenticular changes in the 94 affected eyes^*

Lenticular changes	No. Eyes	(%)	BCVA**
None	38	(40.4)	0.7 ± 0.2
Mild/Moderate	26	(27.7)	0.4 ± 0.3
Severe	30	(31.9)	0.02 ± 0.02

^*Recorded on last visit before any corrective surgery was carried out.

^**BCVA: best corrected visual acuity expressed as decimal scale units eg, 1.0 is a visual acuity of 6/6 or 20/20 and 0.01 is 6/600 or 20/2000. In practical terms, we recorded 0.01 visual acuity level as the ability to perceive light with accurate projection and 0.02 as the ability to perceive hand movements in front of the affected eye.
