Laser eye surgery is generally not considered painful. During the procedure, you are given numbing eye drops to ensure comfort, and most report feeling only mild pressure rather than pain. The entire surgery typically takes just a few minutes per eye, and discomfort is minimal. Post-surgery, some people may experience mild irritation or a gritty sensation in their eyes for a few hours to a couple of days, but this is manageable with eye drops that we give you to take away.

Combining distributions of aerosols and reactive gases with long-lived GHGs and ODSs enables disentangling of the processes that regulate atmospheric chemistry: emissions, transport, cloud processes, and chemical transformations. ATom analyzes measurements using customized modeling tools to derive daily averaged chemical rates for key atmospheric processes and to critically evaluate Chemistry-Climate Models (CCMs). ATom also differentiates between hypotheses for the formation and growth of aerosols over the remote oceans.

Blended Vision, also known as monovision, is a tailored approach to vision correction that addresses presbyopia (age related need for reading glasses) by optimising one eye for distance vision and the other for near vision. This technique can be achieved through various surgical methods, including LASIK, LASEK, or Smartsight™. The brain adapts to this setup by blending the images from both eyes, allowing for clear vision across a range of distances without the need for reading glasses. Blended Vision is particularly beneficial for those over 40 experiencing age-related near vision decline. It offers a practical and effective solution to maintain visual independence and improve overall visual function in everyday activities.

The Harvard QCL CO2 instrument measures CO2 concentrations in situ using a thermoelectrically cooled pulsed-quantum cascade laser (QCL) light source, gas cells, and liquid nitrogen cooled solid-state detectors. The CO2 mixing ratio of air flowing through the sample gas cell is determined by measuring absorption from a single infrared transition line at 4.32 microns relative to a reference gas of known concentration. In-flight calibrations are performed by replacing the air sample with reference gas every 10 minutes, and with a low-span and a high-span gas every 20 minutes.

LASEK is a laser eye surgery option that combines elements of LASIK and PRK (Photorefractive Keratectomy). It is particularly suitable for patients with thin or irregular corneas and who are not suitable for LASIK. During the procedure, the outer layer of the cornea (epithelium) is gently loosened and moved aside. The underlying corneal tissue is then reshaped with a laser to correct vision imperfections. The epithelial layer is repositioned afterward, acting as a natural bandage while the eye heals.  LASEK offers similar vision correction benefits to LASIK but with a surface approach, making it an excellent option for those with specific corneal conditions or dry eyes. We also have access to pioneering Smartsurf technology allowing us to do TransPRK using a no touch technique whereby you can have laser eye surgery without us having to make any contact with your eye.

Discover how laser vision correction at OCL Vision can enhance your daily activities and provide the freedom to enjoy life with clear, unaided vision.

Our team will guide you through any necessary paperwork and explain how to use your post-operative eye drops, as well as how to best look after your eyes in the days and weeks following surgery. You will meet your surgeon again before the procedure and have ample opportunity to ask any questions.

This dataset provides atmospheric concentrations of CO2, CH4, CO, and N2O measured by the Harvard Quantum Cascade Laser System (QCLS) instruments during airborne campaigns conducted by NASA's Atmospheric Tomography (ATom) mission. The QCLS (DUAL and CO2) instrument package contains two separate optical assemblies and calibration systems, and a common data system and power supply. The QCLS DUAL instrument simultaneously measures CO, CH4, and N2O concentrations in-situ using two thermo-electrically cooled pulsed-quantum cascade lasers light sources, a multiple pass absorption cell, and two liquid nitrogen-cooled solid-state detectors. The QCLS CO2 instrument measures CO2 concentrations in-situ using a thermoelectrically cooled pulsed-quantum cascade laser light source, gas cells, and liquid nitrogen cooled solid-state detectors. The CO2 mixing ratio of air flowing through the sample gas cell is determined by measuring absorption from a single infrared transition line at 4.32 microns relative to a reference gas of known concentration. The ATom mission deployed an extensive gas and aerosol payload on the NASA DC-8 aircraft for systematic, global-scale sampling of the atmosphere, profiling continuously from 0.2 to 12 km altitude. Flights occurred in each of 4 seasons from 2016 to 2018.

Your prescription should be stable, ideally unchanged within the last two years, to ensure that the surgery will be effective. Laser eye surgery is most straightforward in people with a prescription range between -10D and +7.25D.

LASIK is a popular refractive surgery designed to correct common vision problems such as myopia (short-sightedness), hypermetropia (long-sightedness), astigmatism, presbyopia (reading vision problems) or any combination of these. During the procedure, our expert surgeons use a specialised low energy gentle femtosecond laser to create a thin flap in the cornea. This flap is then lifted, and the underlying corneal tissue is reshaped using an excimer laser. This precise reshaping allows light entering the eye to be properly focused onto the retina, resulting in clear vision. LASIK is renowned for its quick recovery time, high success rates, and minimal discomfort, making it an excellent choice for those seeking freedom from glasses and contact lenses.

Great experience with Dr Chien Wong and his team. I needed to have three separate operations to repair a detached retina and poor NHS interventions. Amazing care and treatment and 2 years later still very grateful for their efforts.

The entire experience, from early tests to the surgery and post-surgery care has been nothing but exceptional! I had my surgery in December and whenever I've needed any help or had any concerns, the entire team, from the receptionists to nurses and Dr Laura have been magical. I would highly recommend OCL Vision!
