title: [The visual functional therapeutic effects of deep lamellar keratoplasty and penetrating keratoplasty for fungal corneal ulcer].
abstract: OBJECTIVE
  To investigate the visual functional therapeutic effects of deep lamellar keratoplasty (DLK) and penetrating keratoplasty (PK) on perforated fungal keratitis.
  
  
  METHODS
  64 patients (64 eyes) of fungal corneal ulcer in Ophthalmology Center of Ningbo Yinzhou People Hospital from 2004 to 2009 were retrospected, of which undergo DLK (36 patients, 36 eyes) and PK (28 patients, 28 eyes), and followed up by 12 to 24 months. Check two sets of patients' VA and refraction before operation, and analyze the best-corrected visual acuity (BCVA), corneal refraction changes, corneal endothelium counting and complications, using χ(2) test and t-test.
  
  
  RESULTS
  The BCVA after the operation of two sets are both improved, 32 eyes of DLK set were above 0.4, 19 eyes of PK set were above 0.4, of which the DKL set is a bit better than PK set (χ(2) = 4.304, P > 0.05). The astigmatism of DLK set is smaller than the PK set after operation, and there is significant difference (χ(2) = 4.98, P < 0.05). The astigmatism of two sets on the average were all no more than 5.00 D. The reject reaction of keratoplasty of DLK is less than PK, there is obviously significant difference (χ(2) = 34.17, P < 0.05).
  
  
  CONCLUSIONS
  There is less complications of DLK than PK for fungal corneal ulcer. DLK can reduce the occurrence of reject reaction of endothelium type, and the BCVA, refraction of DLK after operation is similar to PK, the incidence rate of surgical operation failure is low.
