Interested in Refractive Eye Surgery?

In the case of nearsightedness, farsightedness, astigmatism, or presbyopia refractive surgery can help either reduce or eliminate the need for glasses/contacts and improve vision. Good candidates include:

  • Patients with stable unchanging refractive errors
  • Patients with thick healthy corneas and good overall ocular health
  • Patients whose lifestyle/expectations match the surgery they choose

Candidates may have limited options or should avoid refractive surgery if they have:

  • thin corneas
  • severe dry eye
  • extreme levels of myopia, hyperopia, or astigmatism
  • corneal scars
  • cataracts
  • history of eye infections or an active eye infection
  • diabetes
  • glaucoma

What to expect with refractive eye surgery

Before your surgery, your optometrist will:

  • Discuss options and expectations associated with the different types of refractive eye surgery
  • Test your vision
  • Measure the surface and thickness of your cornea
  • Double check if any other existing conditions may complicate or prevent a successful outcome

During your surgery, your doctor will:

  • Instill numbing eye drops
  • Instill devices around your eyelids to prevent blinking
  • Have the patient will stare at a target light to prevent from moving
  • Clicking sounds, duration, other details may vary between different types of surgeries

After your surgery, you will:

  • Use a see through shield to protect your eye while it heals for a few days
  • Apply eye drops to reduce dryness and promote healing
  • Experience varying amounts of scratchy/burning sensations temporarily

Be sure to discuss with your eye care provider about the varying types of refractive surgery options and if they are right for you. Some of these include: LASIK, PRK, ICL, LRI, SMILE etc.

Do I Need a Contact Lens Fitting?

Why do I need to be fitted for contact lenses? Did you know your glasses prescription is different from your contact lens prescription? When an optometrist fits you for contact lenses, they are ensuring several things:

  • Your eye is healthy enough to be wearing contact lenses. Conditions such as dry eyes and allergic conjunctivitis need to be treated before you can wear contact lenses. Eye conditions such as corneal scars, dystrophies, and/or irregular surfaces may require a fitting with specialty lenses.
  • The contact lens is the right type for your life style. Based on your occupation, extracurricular activities, and other needs, we can help you determine whether dailies, bi-weekly, or monthly contact lenses will meet your needs.
  • Finding a comfortable fit with good vision. We take measurements of your eyes to fit you in a comfortable lens. Many companies make contact lenses, and each have a set of parameters they work with. We can check if a lens is too tight or too loose on your eyes, how the contact lens moves when you blink, and whether it is centered on your eye. We also ensure each eye sees well both at a distance and near.

In addition, we first train new contact lens wearers on how to safety insert and remove contact lenses. We will go over the cleaning process, to ensure that lenses are handled safely because any buildup of proteins and debris on the lenses can cause damage to the cornea.

MiSight Contact Lenses

Myopia, or nearsightedness, is a condition which causes distant objects to appear blurry. It is a particular concern with children, because myopia results in the lengthening of the eyeballs. As children’s eyes continue to grow, so does the progression of myopia. As a result, the retinal tissues gradually stretch, which can increase the risk of eye diseases later in life. Luckily, CooperVision’s MiSight 1 day lenses are an effective and child-friendly solution to managing myopia progression!

它们如何工作？

The MiSight 1 day lenses are the first soft contact lenses proven to slow down the progression of myopia, through the use of ActivControl technology. When inserted on the eye, the center of the lens improves distance vision by correcting the refractive error and the concentric peripheral rings allow for myopic defocus. This defocusing is what is believed to reduce further lengthening of the eyeball, effectively impeding the progression of myopia. Not only have the MiSight 1 day lenses been clinically proven to slow down the progression of myopia by 59%, they are also comfortable to wear and easy to handle. In a three-year long study conducted on the MiSight 1 day lenses on children ages 8 -15 years, 90% of children reported that they preferred their MiSight 1 day lenses compared to their glasses and 90% of children were able to insert and remove the lenses on their own. Further, 100% of parents stated that their children were happy with their overall experience with the MiSight 1 day lenses, including the comfort, vision, ease of use, and freedom from glasses!

Progent – 勤奋的隐形眼镜清洁剂

您的 Ortho-K 隐形眼镜或 RGP 镜片是否开始变得刺激和不舒服？您是否曾感觉眼前一片模糊？正在寻找一种简单有效的方法来深度清洁您的镜片？在 Eyelab，我们员工最喜欢的产品之一是 Progent 镜片清洁剂。

它是如何工作的？

Progent 通过松开和去除隐形眼镜上随着时间的推移而积累的蛋白质沉积物来清洁镜片。它可以有效去除所有 Ortho-K 隐形眼镜和 RGP 镜片上的表面蛋白质，而无需手动擦拭，以免损坏镜片。该产品不仅提高了镜片佩戴的舒适度，还有助于维护眼睛健康并延长镜片的使用寿命。 Progent 深层清洁镜片比日常清洁产品更有效。

它配有两种解决方案：Progent A（次氯酸钠）和 Progent B（溴化钾），它们在氧化还原反应中协同作用，深层清洁表面涂层，无需典型清洁中使用的研磨剂或机械摩擦。只需三十分钟，它就能有效消毒所有可能污染镜片的微生物，包括酵母、霉菌、细菌和病毒。

来源： 明尼康网

说到这里，你可能想知道这个清洁器到底有多少复杂的步骤？简单的答案是，只需混合 A 和 B 溶液，摇匀，然后等待！只需将镜片浸泡 30 分钟 – 无需擦拭。通过每 3 个月使用一次这种清洁剂（或者根据需要更频繁地使用），您的隐形眼镜可以保持抛光和良好维护，以更好地服务于您的视力。

PRK 激光眼科手术后 8 年

在上一篇文章中，我谈到了我在2014年接受激光眼科手术的经历。八年后的今天，我对自己接受手术的决定感到非常高兴。我的视力仍然稳定在 20/20，但我仍然时不时地感到干眼。

手术的最大优点之一是能够在早上醒来并立即看得清楚。这次手术让我能够在半夜更好地照顾我的双胞胎女儿，而不必先找到我的眼镜。我也不必再担心在玩极限飞盘或进行其他体育活动时隐形眼镜或眼镜脱落。手术后我开始意识到生活中一个较小的变化是我不再需要随身携带超细纤维布来清洁眼镜。

然而，现在我已经到了老花眼影响的年龄 （眼睛逐渐丧失聚焦附近物体的能力） 变得更加突出，我可能需要使用老花镜。总的来说，我很高兴我决定接受 PRK，并且我对此并不后悔！

预约眼科实验室 了解更多关于您是否适合接受激光眼科手术的信息，并讨论您可能有的任何问题或疑虑！

温哥华首家测量眼轴长度的验光诊所

今年一月，我们诊所用全新的“玩具”迎接了新年—— MYAH 来自 Topcon，使我们在 Eyelab 成为温哥华第一家验光诊所之一 测量并绘制眼轴长度图表.您可能想知道……轴向长度测量有什么好处？为什么我们关心眼球有多长？

随着眼睛长度的增加，我们的镜片处方量不仅会增加，而且患眼部疾病（如青光眼、白内障、黄斑变性）的风险也会增加。事实上，儿童近视的快速发展是由于眼球过度伸长所致。因此，为了监测近视管理治疗的有效性，每次随访时都会记录眼轴长度测量值，作为我们近视管理计划的护理标准。对于 Ortho-k 镜片患者，眼轴长度是用于评估近视进展的主要指标之一。

MYAH 可以帮助我们进一步推进近视管理护理以及干眼症的诊断和管理。

干眼评估

无创撕裂时间 (NIBUT) 测量

在 Eyelab，我们可以通过无创地准确测量泪液破裂时间来评估泪膜的稳定性。通常，泪膜破裂时间约为 10 秒——泪膜破裂时间较短，尤其是低于 5 秒，表明存在干眼症。

睑板腺成像

睑板腺是嵌入我们眼睑的油腺，它产生泪膜的脂质层，并在我们眨眼时表达。成像腺体允许医生分析它们的形状和结构。健康的腺体在图像中会显得长而连续，有助于眼睛产生油脂以进行润滑。相比之下，不健康的腺体会因退化和浓缩而显得短得多，从而产生“牙膏”稠度的油脂，或者完全堵塞而无法分泌油脂。

隐形眼镜配件

MYAH Topcon 还允许我们的医生模拟荧光成像，以观察 Ortho-K 和 RGP 隐形眼镜的适配度。这种非侵入性方法可以高效准确地评估镜片是否能舒适地戴在眼睛周围并提供有效的治疗。

在了解了我们诊所新机器的酷炫功能后，您是否想亲自尝试其中的一项服务？不要犹豫——今天就与我们预约吧！

用于近视管理的新型创新镜片

世界上最常见的眼部疾病之一是近视，即无法清楚地看到远处的物体。近视进展的一个问题，特别是对于成长中的儿童来说，是眼球轴长的增加，这会增加患青光眼、白内障、视网膜脱离等眼部疾病的风险。

据估计，到 2050 年，全球一半的人口可能会受到近视的影响。研究表明，花在近距离工作活动（例如计算机工作）上的时间越多，患近视的可能性就会增加。幸运的是，有一个独特且创新的解决方案可用：HOYA 的 MiyoSmart 镜片！它们是控制近视进展的非侵入性有效选择。

来源：HOYA Vision

它们如何工作？

MiyoSmart 镜片是采用散焦合并多段 (DIMS) 技术的矫正镜片。镜片的中心可矫正屈光不正以改善远视力，而外围蜂窝图案可保持恒定的近视散焦。

来源：HOYA Vision

临床证明，在提供清晰视力的同时持续进行近视散焦可以抑制眼球伸长并减缓近视加深。事实上，一项研究发现，佩戴采用 DIMS 技术的 MiyoSmart 镜片的参与者的近视进展平均减少了 59%。它们由抗冲击材料制成，并提供 100% 紫外线防护，非常适合任何拥有积极生活方式的人！
