The child has broken multiple pairs of glasses and refuses to wear them. His mother is concerned that he will lose contact lenses and wants him to have something disposable so he will have spares.
OD: +2.75-2.75 x 020; 20/40; SimKs 43.20/46.25
OS: +2.75-4.25 x 160; 20/40; Sim Ks 42.47/46.21
Figure 7. OD and OS topographies showing high regular astigmatism.
See Figure 7 for topographies.
I prescribed custom soft toric monthly replacement contact lenses.
OD: +3.25-3.25 x 010; 8.7 mm base curve; 14.5 mm diameter; 20/25
OS: +3.00-3.75 x 165; 8.7 mm base curve; 14.5 mm diameter; 20/30
The patient very successful with application and removal. At the six-month follow-up visit, his parent reports improved academic success.
Figures 8 (top) and 9 (bottom). High slightly asymmetric astigmatism OD and OS.
Parents report that the patient does not wear her spectacles, and they would like her to try contact lenses.
OD: +0.50-2.50x010; 20/20; SimKs 41.03/43.07
OS: +1.25-2.75x163; 20/30; SimKs 40.44/43.50
Bitoric GPs were designed using a saddle technique and ordered based on an over-refraction on Pl/-3.00; 41.00/43.00; 9.2 mm diagnostic lenses.
Figures 10 (top) and 11 (bottom). Very high regular astigmatism with no evidence of ectasia.
Final lenses were:
OD: -0.25/-2.25; 41.00/43.00; 9.0 mm; 20/20
OS: -0.50/-2.50; 41.00/43.00; 9.0 mm; 20/25
The child and parents were successful with application and removal. The patient wore lenses for school with good success.
