Aim: To study the efficacy of collagen crosslinking on pseudophakic bullous keratopathy.
Methods: Fifteen patients with pseudophakic bullous keratopathy participated in the study.
Corrected visual acuity measurement, slit lamp examination, corneal
clarity grading, ocular
pain intensity scale and corneal thickness measurement were performed before corneal
crosslinking and 1, 3 and 6month postcrosslinking. Corneal collagen crosslinking was
performed after the removal of the epithelium and the application of riboflavin every 3
minutes for 30 minutes then the ultraviolet irradiation applied for 30 minutes with the
application of riboflavin every 5 minutes.
Results: The mean age was 65.5 year (9 females and 6 males). Corneal thickness
decreased significantly after crosslinking but the visual acuity did not change significantly
after crosslinking. Corneal transparency improved in the first month. Ocular pain
decreased significantly in the first and third month.
Conclusion: Corneal collagen cross linking is an effective and temporal procedure to
decrease ocular pain for bullous keratopathy patients
The present study aimed to assess the influence of curing
distance on the loss of irradiance and power density of two curing
light devices of two different systems.
Two dental curing devices were used in this study,
Halogen unite (Chromalux 75) and light emitting diodes (LED)
(Bluedent smart),
Curing shrinkage with its resulting stresses inside the restoration, and
microleakage with its resulting marginal discoloration are the most important problems that face
composite restorations. The new studies try to use a lot of ways to reduce it.
One of these ways is using
soft-start light curing.
Investigate the clinicale influence of using soft start light curing method on marginal discoloration of
composite restoration of primary molars.
