Objective To analyze the accuracy of IOL power formulas (SRK-T and Hoffer-Q) in predicting IOL power for patients with high myopia cataract and short eye axis cataract.

Relationship of refractive status,axial length,and scleral metamorphic change in chicken form deprivation eyes;

Reliability of the IOL-Master in measuring axial length and anterior chamber depth in biphakic eyes;

Relationship of diopter,axial length and intraocular pressure for teenagers with myopia;

Effect of ocular axis length and diopter on mean retinal nerve fiber layer thickness;

IOP, refractive error, corneal curvature and ocular axis were measured in both eyes and the influence of age, ocular char- acteristics, refractive error, refractive status (myopia, emmetropia, hypermetropia), corneal curvature and the ocular axis on IOP was analyzed with SAS 8.

The measurement of eye axial length by ultrasound;

The Comparison of the Accuracy of the Measurement for Myopia Patients Axial Length via A-scan and IOL-Master;

The evaluation included refraction,corneal curvature radius,corneal topography and axial length.

Statistical analysis on axis oculi and keratometry of cataract patients;

Eyesight and axis oculi in b.

Objective: To measure intraocular pressure (IOP) and axis oculi onchoriodal detachment associated with retinal detachment by differentopertations preoperatively and postoperatively.
