... [ 14 ]. Additionally, FSLs have been used to create arcuate incisions to correct high astigmatism in post-keratoplasty corneas [ 15 , 16 ]. FSL systems have been used to create trephinations and dissections both in donor and recipient tissue in PK, anterior lamellar keratoplasty (ALK) and Descemet...

... Abstract Phakic intraocular lenses (pIOLs) implantation concerns high ametropia. Initially developed for high myopia correction, the treatment fields were expanded to astigmatism and hyperopia corrections. Three basic types of pIOLs allow these corrections: anterior chamber IOLs, iris-fixated...

.... The main symptoms are increasing irregular astigmatism and a decrease in best-corrected visual acuity. Corneal topography may reveal the disease early and is very useful in detecting progression. Inferior corneal steepening is the most common topographic finding. Management of keratoconus includes the use...
