Reduced Schematic Eye To make simple optical calculations a Reduced Schematic Eye, based on Gullstrand’s model, was later developed that approximately matches the ocular dimensions but simplifies the calculations by combining all the refracting surfaces into one power and location and all the refractive indices into one. Schematic Eye Models • 1924 - Gullstrand made a six surface eye model (crystalline lens with a high index core and a lower index shell). Later reduced to four surfaces since raytracing is time consuming. • 1952 - Emsley made a single surface model for simplicity and speed of raytracing. Today, computers can quickly raytrace eye models, so Reduced eyes have a genealogy stretching back 360 years to Huygens. 6 - 8 The best known example is Emsley's reduced eye 7 (Figure 6 A), with a power of 60 D produced by a corneal radius of curvature of 50/9 mm (or 5.55 • mm) and a refractive index of 4/3 (or 1.33 •). The Schematic Eye of Gullstrand or the Reduced Eye of LeGrand, are technically based on a paraxial optical analysis.

Gullstrand #1 Exact Eye It is for reference purposes, to show how multiple surfaces can be reduced systemmatically to a single thin lens equivalent Reduced Eye Simplifications: The reduced schematic eye treats the eye as if it were a single refracting element consisting of an ideal spherical surface separating two media of refractive indices of 1.00 and 1.33.

Of these schemes is the most accurate is reduced eye proposed C. K. Verbitsky, as can be seen from the comparison of some value for schematic eyes of Gullstrand and R., proposed by some authors (see table). Eye and medical performanceListing's reduced eye gauss's theorem Homocentric system of lens Gullstrand schematic eye Nodal point Focal pointPrinciple point The reduction of the Gullstrand ratio is dependent on the amount of laser ablation (Figures 3 and 4). For example, if the Gullstrand ratio is 0.7 (ie, as a result of a 7.00 D ablation; Figure 3), the difference between the true corneal power and the K reading is approximately 2.00 D. However, for the normal cornea (Gullstrand ratio, 0.83), the View VISN1221_Tutorial_ Problems_Week 1_2020 (1).pdf from VISN 1221 at University of New South Wales.

A schematic eye based on 6 refractive surfaces (2 for the cornea and 4 for the crystalline lens to account for the variation of the refractive index of the lens) was defined by Gullstrand. 4 This schematic eye model is known as the Gullstrand's exact eye or Gullstrand's number 1 eye.

Reduced Schematic Eye. To make simple optical calculations a Reduced Schematic Eye, based on Gullstrand’s model, was later developed that approximately matches the ocular dimensions but simplifies the calculations by combining all the refracting surfaces into one power and location and all the refractive indices into one. Schematic Eye Models • 1924 - Gullstrand made a six surface eye model (crystalline lens with a high index core and a lower index shell). Later reduced to four surfaces since raytracing is time consuming. • 1952 - Emsley made a single surface model for simplicity and speed of raytracing. Today, computers can quickly raytrace eye models, so A good example is the Gullstrand number 2 eye as modified by Emsley — the Gullstrand‐Emsley Eye 7 (Figure 6B). This comes in relaxed and 10.9 D accommodated forms, with the lens moving forward and being more curved in the latter. Four Refracting Surfaces.
