For the post-LASIK cornea, how-ever, the Gullstrand ratio is reduced, and the keratometer-reported K reading will overestimate the true corneal power. Again, the formula will think the IOL power should Recent work by Dubbelman et al. (2002, 2006) using Scheimpflug photography show the Gullstrand ratio to range from 0.82 to 0.84. These new results may call for a modification of the corneal power model.

The challenge with post refractive corneas is that the Gullstrand ratio of the anterior to the posterior corneal curvature is no longer given. This leads to two main issues. Firstly, the K-readings are reported too flat with the cornea after an intervention to correct myopia and too steep for a prior hyperopic patient.

For this work, he received the Nobel Prize in Physiology or Medicine in 1911. Allvar Gullstrand, född 5 juni 1862 i Landskrona, död 28 juli 1930 i Stockholm, var en svensk ögonläkare och uppfinnare; professor i oftalmiatrik vid Uppsala universitet 1894, i fysikalisk och fysiologisk optik 1914, mottog 1911 Nobelpriset i fysiologi eller medicin.

(2002, 2006) using Scheimpflug photography show the Gullstrand ratio to range from 0.82 to 0.84. These new results may call for a modification of the corneal power model. According to the correlation analysis, the minimum AP ratio was 1.11, which is close to the AP ratio in the Gullstrand schematic eye model.

The famous Gullstrand eye model, for example, utilizes a fixed anterior posterior corneal curvature ratio (APR) of 0.883. Keratometry respects this fixed APR by modifying the corneal refractive index to the so-called keratometric index (e.g., 1.3315, Olsen 1986). RX: AXL ratios for participant data were compared with the ratio generated from Gullstrand model eyes. Both modelled and actual data showed non‐linearity and non‐constancy, and that as axial length is increased, the relationship between myopia and axial length differs, such that it becomes more negative.

According to the Gullstrand schematic eye model, the anterior corneal radius, posterior corneal radius, and AP ratio (anterior corneal radius/posterior corneal radius) are 7.7, 6.8, and 1.13 mm, respectively.
