AUTOREFRACTOMETRY OR OPTOMETRY      Refraction being the most commonly performed optical procedure has been widely developed.      Though the conventional technique of retinoscopic refraction is an excellent method of objective refraction, it is a time-consuming procedure and not every practitioner manages to accomplish it accurately.      The refractometry (optometry) is an alternative method of finding out error of refraction by use of an optical equipment called refractometer or optometer.      Refraction being the most commonly performed optical procedure has been widely developed.      Though the conventional technique of retinoscopic refraction is an excellent method of objective refraction, it is a time-consuming procedure and not every practitioner manages to accomplish it accurately.      The refractometry (optometry) is an alternative method of finding out error of refraction by use o...

LENSOMETRY OR FOCIMETER OR VERTOMETER:       Lensometry is a procedure used to measure the prescription of a patient's existing eyeglass lenses or the power of contact lenses. This technique is often called neutralization, but should not be confused with neutralization as the word applies to retinoscopy. Lensometry is performed (usually by the ophthalmic medical assistant) with a specialized instrument knows as a lensometer.        Lensometry measures four principal properties of Lenses:           1. Spherical and Cylindrical power in dioptres.           2. Axes, if the lenses have a cylinder component.           3. Presence and direction of a prism incorporated into the lenses.           4. Optical centers.        Lensometry performed on a patient's eyeglasses before refraction can provide a starting point for the current ref...

MEASUREMENTS IN FITTING EYEGLASSES      For eyeglasses to be effective, patients must feel satisfied with the prescription and the overall fit of the lenses of the face. Eyeglasses that fit improperly may cause vision problems. To help determine the source of a patient's dissatisfaction or discomfort with eyeglasses, ophthalmic medical assistants may need to measure interpupillary distance, vertex distance, and the base curves of the lenses.       Interpupillary distance (abbreviated IPD or PD) is the distance from the center of the pupil of the other eye. IPD is important to the laboratory technician who makes eyeglass lenses because it indicates where to place the ground optical centers in the finished lenses so that they lie directly in front of the patient's pupils. The optical center of a lens denotes the point of optimal vision; it is the single point through which light may pass without making being bent or changed (Fig 1.1) Fig 1.1 Relationsh...

 EXAM TIPS FOR OPTOMETRY STUDENTS - II YEAR 1.Always stick to the given syllabus. Download the syllabus and plan your schedule. 2.Check last 5 years previous question papers and plan accordingly. 3.In PAPER I & PAPER II, timing matters a lot. So, how you are giving time for each questions which helps to score good marks. 4.Follow this hierarchy for paper I and note down the questions from previous year question papers or Q-BANK. a. ANATOMY b. PHYSIOLOGY c. PATHOLOGY d. PHARMACOLOGY e. VISUAL OPTICS         f.  OPHTHALMIC INSTRUMENTS 5.Draw diagrams neatly and mark the parts which helps to score good marks. Presentation will give you extra marks. 6.Exam timings will be 10:00 AM-01:00 PM. So, during the study days, plan this timing for self-evaluation test, avoid sleeping during this hours. 7.Question pattern will be divided into 2 sections. Each sections will have two 16 marks(2+2=4 16marks) and three 6 marks(3+3 = 6 6marks). 8. Study,E...
