Purpose:
|
To report the pre- and post-operative findings of a case with dysfunctional lens syndrome.
|
|
Methods:
|
An adult patient was evaluated using iTrace aberrometer, Tomey topographer and slitlamp biomicroscopy to confirm dysfunctional lens syndrome.
|
|
Results:
|
A 45-year-old male patient presented with the chief complaint of poor visual quality; uncorrected and best corrected visual acuity 0.5 and 0.8 in the right eye, respectively and with refraction Plano/-1.50×80 (SE= -0.75D). Pre- & post-operative root-mean-square (RMS) of total higher-order aberration in the entire eye, the internal optics and the cornea were 0.350 & 0.257, 0.311 & 0.236 and 0.214 & 0.191 micron (µ), respectively. Also, the magnitude of preoperative total, internal and corneal coma was 0.254µ×222º, 0.274µ×242º and 0.097µ×131º and postoperative values were 0.170µ×162º, 0.131µ×177º, 0.054µ×125º, respectively.
|
|
Conclusion:
|
Sometime the HOAs of the internal optics, mainly crystalline lens, are not compensated by the cornea and this may cause visual discomfort in the absence of any significant cataract, this situation is known as dysfunctional lens syndrome (DLS).
