1. How is the relative lens vault (rLV), the novel biometric factor, calculated? (a) The ratio of lens vault to anterior vault (b) The sum of lens vault and anterior chamber depth ( c) The ratio of lens vault to anterior chamber depth (d) The ratio of lens vault to axial length (e) The ratio of lens thickness to axial length 2. Which one of the following statements is incorrect? (a) A-scan ultrasound biometry produced more hyperopic results than the IOLMaster. (b) All formulas showed a slight tendency toward resultant hyperopia ( c) Haigis formula produced the most myopic results (d) Hoffer Q formula produced the least prediction error (e) About 60% showed refractive error less than 0.5D 3. Which of the following factors contribute to hyperopic shift after cataract surgery in angle closure eyes? (a) Anterior chamber deepening (b) IOL shift to posterior plane ( c) Intraocular pressure decrease (d) Pupillary block component removal (e) All of the above 4. True or false? The rLV combines the effect of lens thickness, lens position and anterior chamber depth. 5. Which one of the following statements is TRUE? (a) The multivariate analysis showed that only the lens vault was related to postoperative refractive error (b) High rLV were associated with increased postoperative refractive error ( c) The rLV showed negative correlation with postoperative refractive error (d) The anterior vault showed positive correlation with postoperative refractive error (e) There was a significant linear correlation between mean refractive error and anterior chamber depth
