PRK with PTK for treatment of patients because of the serious irregular astigmatism

192 days ,[link widoczny dla zalogowanych], the use of eye drops Xiao BRIGHTWAY human cornea , the use of PI1 ( range 20 right 5.00D.St3 = b = 0.15-3.00D, corneal procedures , cutting depth were 10tan, then use the PRK procedure. surgery Amount of design icons one by one O.50D.Cx18O +1.0 terrain irregular astigmatism 3.00D.S = b = a 1.00D.Cx30 ~, after 1 month , visual acuity right eye 1.0, angle × Year-old film transparent. OPHTHALMOLOGY China Volume 1 2001 1 53 PRK after discussion , resulting in corneal irregular astigmatism due to diverse, nothing more than laser equipment ,[link widoczny dla zalogowanych], doctors and patients the level of cooperation and biological response . clinical concern is when the re- treatment with laser surgery . According to the clinical observation of nJ, PRK 6 months postoperatively , corneal response was relatively stable . Hanna [2] that after 6 months, disable the hormone and other drugs, observed in March Stability before refractive surgery. We once again to 5 in the eyes of laser surgery , including four in the first 41 days that the laser is still achieved very good results, follow-up one year efficacy and stability , it appears that a large number of patients needed long-term follow-up after Can the most appropriate time for the laser again to conclusions . cases of corneal irregular astigmatism , irregular corneal surface uneven , this is obviously seen from the topography . When the PTK procedure , the surgical field was uniform laser irradiation Cutting ,[link widoczny dla zalogowanych], uniform cutting depth . Therefore, viscosity must have a certain eye drops , such as Alice , BRIGHTWAY Xiao ,[link widoczny dla zalogowanych], Su Gao Jie therapy, or a large number of mucus elasticity agent, drops in the cornea , the eye is horizontal , the laser Tangent to the top beam and perpendicular to the cornea until a moment later , the corneal mucus filled cavity , and the raised face is still exposed to the space, laser treatment, only the outstanding part of the space to be cut , while the concave due to mucus filled , the laser is mucus Absorbed by the Department of corneal tissue does not produce laser cutting effect, therefore , the laser PTK procedures , the corneal surface can become smooth,[link widoczny dla zalogowanych], correction of irregular astigmatism , PRK procedure and then use the remaining refractive error correction state. from our 5 efficacy of view, to the purpose of correcting irregular astigmatism , corneal topography get proof from the surgery .
