Hyperopic Automated Lamellar Keratoplasty

Customized Topography-guided Photorefractive Keratectomy With the MEL-70 Platform and Mitomycin C to Correct Hyperopia After Radial Keratotomy

“…Muñoz et al15 described a case of bilateral corneal ectasia after LASIK for low myopic astigmatism in a patient with previous RK and astigmatic keratotomy. Corneal ectasia can also occur with hyperopic automated lamellar keratoplasty after RK, as shown by Lyle and Jin 6. They reported a 26% incidence of iatrogenic ectasia.…”

“…Corneal ectasia can also occur with hyperopic automated lamellar keratoplasty after RK, as shown by Lyle and Jin. 6 They reported a 26% incidence of iatrogenic ectasia. To our knowledge, there are no reported cases of ectasia with PRK after RK.…”

The cornea in young myopic adults

“…This not only confirmed the ethnic difference in the corneal thickness but also aroused further consideration in refractive surgery. Lyle and Jin have reported an incidence as high as 26% of progressive corneal ectasia termed iatrogenic keratoconus following a 52%–70% cutting depth in hyperopic automated lamellar keratoplasty 41. In Wang's study, posterior corneal bulge following LASIK surgery is correlated with the residual corneal bed thickness and the risk of ectasia may be increased if the residual corneal bed is thinner than 250 μm 42.…”

Optical Profile Following High Hyperopia Correction With a 500-Hz Excimer Laser System

“…Several techniques were developed for the hyperopia correction, but the outcomes obtained were poor. [33][34][35][36][37] Clear lens extraction is less accurate and predictable for hyperopia less than +3.00 D and as a treatment of high hyperopia it raises concerns about its irreversibility and loss of accommodation. Furthermore, it can produce cystoid macular edema and retinal detachment, so it is primarily reserved for patients older than 45 years or those with some degree of lens opacification.…”
