Title: Method for reshaping the cornea
Inventor: BILLE JOSEF F
IPC: A61F9/01
Filed: 1990-04-05
Abstract: ABSTRACT      A method for  reshaping  the cornea comprises an  initial step of determining the precise volume of corneal tissue which must  be  removed  in  order  to  attain  the  desired  vision correction.  A pulsed laser beam, having a pulse energy density sufficient to cause photoablation of corneal tissue near the threshold of the plasma regime,  is directed onto the eye for removal  of  relatively  large  portions  of  tissue  from  the precisely determined volume to establish a corrected surface.          A pulsed laser beam, having a pulse energy density sufficient to cause photoablation of corneal tissue substantially below the threshold of the plasma regime, is then directed onto the corrected surface to take away  relatively small portions of corneal tissue and thereby smooth the corrected surface.

It is  for topical cutaneous application  as  a  prophylactic,  diagnostic aid and/or remedy during the latent or clinical stage of systemic lupus     erythematosus,     vasculitis,     sarcoidosis, amyloidosis, rheumatoid arthritis, osteoarthrosis, acne, comedos,  psoriasis,  tinea,  onychia,  paronychia,  corns, callosities, alopecia and indolent tropical ulcers. The novelty of the invention lies in the ability of the said product  to  elicit  a  skin  reaction  at  the latency-reactivation  sites  where  the  causative  agent  of  the above-mentioned maladies resides,  while bringing on no such reaction in the rest of the skin. Hitherto it has not  been  known,  nor  used,  in  the  art  that  such composition  of  matter  applied  onto  the  skin  of susceptible  subjects  can  at  first  elicit  pustules, papules and/or weals,  then heal resulting ulcers,  and that  with  their  débriding  and  the  removal  of  the necrosed tissue of the latency-reactivation sites it is feasible  to  eradicate  the  causative  agent  (primary stimulus,  persistent  antigen)  from  the  skin,  thus healing the  lesions and  arresting the development of these  maladies  at  that  particular  stage.  The  said product  may  also  prove  useful  in  research  into  the above-mentioned and other maladies.  The skin reaction the said product can elicit serves as an indicator of the above-mentioned maladies during their asymptomatic latent period.
