The aim of this study was to compare stereoacuity before and after KAMRA corneal inlay implantation for the correction of presbyopia.
This is a prospective study of 60 patients who underwent KAMRA inlay implantation. Patients were examined before and 6 months after surgery for stereoacuity, uncorrected distance visual acuity (UDVA), and uncorrected near visual acuity (UNVA).
The mean stereoacuity before surgery was 29.5±28.1 arcsec (range: 20-200) and at 6 months was 29.8±26.4 arcsec (range: 20-200). The decline in stereoacuity was not statistically significant. At 6 months follow-up, UDVA was 20/25 or better in all 60 patients and UNVA was J2 (20/25) or better in 51 (85%) patients.
There is no significant change in stereoacuity following KAMRA inlay implantation. The KAMRA inlay is a good treatment option for improving near vision in presbyopic patients while preserving stereoacuity and distance vision.
本研究的目的是比较KAMRA角膜镶嵌植入术矫正老花眼前后的立体视锐度。
这是一项对60例行KAMRA镶嵌植入术患者的前瞻性研究。在手术前及术后6个月对患者进行立体视锐度、未矫正远视力（UDVA）和未矫正近视力（UNVA）检查。
术前平均立体视锐度为29.5±28.1角秒（范围：20 - 200），术后6个月为29.8±26.4角秒（范围：20 - 200）。立体视锐度的下降无统计学意义。在6个月的随访中，所有60例患者的UDVA为20/25或更好，51例（85%）患者的UNVA为J2（20/25）或更好。
KAMRA镶嵌植入术后立体视锐度无显著变化。KAMRA镶嵌植入术是改善老花眼患者近视力同时保留立体视锐度和远视力的良好治疗选择。
