Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Absolute divergence between the individual squint angle (after three months) and the individually aimed squint angle (presurgically agreed on) in intervention group and control group, measurement of strabismus angle by using the alternating prism-cover-test | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Divergence in the subgroups strabismus divergens / strabismus convergens 2. Divergence in the subgroups glasses wearers, contact lens wearers and emmetropia 3. Divergence in the subgroup with axial length more than 25 mm 4. Divergence in the subgroup with axial length less than 21 mm 5. Dependence of the dose-response-correlation of the axial length 6. Correlation between refractivion and axial length 7. Correlation between dose-response-correlation and presurgical sqint angle 8. Divergence in the subgroup with hyperopia more than +2 dpt 9. Divergence in the subgroup with myopia more than -2 dpt | — |
