Brief Summary:
Due to the instability of the tear film, the biometry often needs to be done multiple times in a clinical environment. The high variability of both short-term and long-term repeatability in keratometry of dry eyes is well-known. Consequently, enhancing the condition of the eye surface in individuals with dry eyes will result in improved precision when choosing the power of intraocular lenses (IOLs). This prospective and before-and-after self-control study will recruit 100 patients.
Detailed Description:
Over the past ten years, surgery has progressed from rejuvenation surgery to refractive surgery, which focuses on enhancing both vision and addressing pre-existing issues that impact visual quality. This is why good surgical outcomes involve thorough preoperative assessment and precise intraocular lens(IOL) power determination. To achieve the intended postoperative refractive outcomes, it is essential to perform an accurate calculation of intraocular lens power (i.e., biometry), which may impact the accuracy of the computation.
Damage to the eye's surface from chronic inflammation and induced tear film hyperosmolarity occurs in DED because tear film homeostasis is disrupted. The changes in tear film dynamics and damage to the ocular surface result in mistakes in optical measures, which in turn affect the results of procedures like cataract surgery that heavily rely on these assessments.
Consequently, enhancing the condition of the eye surface in individuals with dry eyes will result in improved precision when choosing the power of intraocular lenses (IOLs).
